Four key materials – several strong properties

Our products originate from a high-quality aluminum alloy that offers simplicity, functionality, and durability for outdoor cooking, while also being lightweight. The Trangia stove is available in various material combinations for windshields, pots and frying pans. Additionally, all parts in the different materials can be purchased separately, allowing the user to customize their own unique combination.

Ultralight aluminium

Our advanced base material is a lightweight material with excellent heat conduction ability. The Ultralight (UL) alloy, also known as 5005, is 50 percent stronger than regular aluminum (alloy 1050). This allows the cookware to be made thinner and the stoves to be lighter without compromising on durability and functionality. This makes it suitable for many users who want a simple, functional, and durable stove.

  • Low weight & excellent heat conduction
  • Soft material, prone to denting

Aluminum and Cooking
Aluminum is one of the most common metals in the Earth’s crust, making it widely used in many things around us. It is also a commonly used metal in kitchen utensils due to its lightweight and excellent heat conductivity. Aluminum is typically not harmful to health when used in cookware. What is recommended by the Swedish National Food Agency is to avoid cooking or storing acidic or salty foods for long periods in aluminum vessels, as they can react with aluminum and release small amounts of the metal into the food. Excessive exposure to aluminum linked to health issues has required extremely high levels of exposure over a very long time.

Things to keep in mind:
• Avoid cooking and storing acidic or salty foods in aluminum vessels for extended periods of time.                                                     
• Maintain and care for your aluminum cookware to prevent scratches and damage that may increase the risk of metal release.
• Use cookware with coating, such as our Nonstick or Duossal pots, as an alternative to aluminum.

Hardanodized aluminium

Hardanodizing is a surface treatment that makes the aluminum surface hard and resistant to scratches, with a gray matte finish. The treatment provides protection against wear and corrosion, and HA aluminum is therefore slightly easier to clean than Ultralight. The weight is the same as the equivalent product in UL because the treatment penetrates the material. Suitable for users who previously appreciated our titanium cookware, as they have the same weight and are scratch-resistant.

  • Low weight & durable scratch-resistant surface
  • More expensive than the base material UL

What is hardanodizing?
Hardanodizing is a surface treatment, an electrochemical process used to create a hard, durable, and corrosion-resistant surface. It involves subjecting the aluminum components to a special electrical treatment and an acidic solution. The process involves the conversion of the upper layer of the aluminum surface into a thick, porous oxide film through electrolytic oxidation. Our hardanodized parts are essentially made of Ultralight aluminum. We apply this treatment to pots, frypans and windshields for our stoves. The hardanodized surface is stronger than regular aluminum and provides improved properties for pots and pans. For windshields, it is more of an aesthetic consideration.

Aluminum and cooking
Please refer to the Ultralight aluminum section for more information.


Trangia’s nonstick is a type of PTFE and is mainly used in our frying pans and pots. Nonstick cookware is made from discs in Ultralight aluminum with a coating. This prevents food from sticking even with little or no cooking oil. This means they are also easy to clean. At the same time, nonstick is more sensitive, and we recommend using only wooden or plastic utensils in these cookware.

  • Easy to clean
  • Less durable coating

Trangia and Nonstick
Our nonstick coating is of PTFE type and free from harmful PFAS substances such as PFOA, in compliance with the requirements of the EU’s chemical directive REACH. The pre-coated aluminum is sourced from European suppliers. The main component of the nonstick layer is PTFE, a non-conductive, water, heat, and chemical-resistant material. PTFE has undergone rigorous testing and does not break down or release harmful gases as long as the pan is not left dry and empty on the heat source at very high heat (above 260°C) frequently and for prolonged periods of time.

Is PTFE on the REACH list of hazardous substances?
No, PTFE (polytetrafluoroethylene) is not included on the European Chemicals Agency’s (ECHA) list of substances of very high concern under the REACH Regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals). REACH aims to regulate and restrict the use of hazardous chemicals in the European Union.

Things to keep in mind:
• Avoid overheating, never leave an empty vessel on the heat source for an extended period of time.
• Before the first use, wash the pot/frying pan and lightly coat with cooking oil.
• Use only wooden or plastic utensils on Nonstick surfaces.
• The Nonstick coating on these camping cookware is thin, and especially the frying pan may need to be replaced from time to time.

Duossal 2.0™

Our unique Duossal 2.0™ super laminate consists of aluminum and stainless steel pressed together under high pressure. It is an optimal combination where the aluminum exterior provides excellent heat conductivity, while the stainless steel interior makes the cookware scratch-resistant and easy to clean. The material thickness is 0.8 mm, with 0.3 mm being stainless steel. This provides sturdy vessels for real outdoor cooking.

  • Durable vessels with optimal heat conductivity
  • More expensive than the base material UL and slightly heavier

What is Duossal?
Duossal technology is used in the manufacturing of pots and frying pans. It combines the advantageous properties of aluminum, such as lightweight and good heat conductivity, with the durable and robust properties of stainless steel. The result is a product that is both lightweight and durable. With Duossal, you get the best of both worlds. Our pots and pans are light enough to easily carry on hiking trips, while retaining the strength needed for challenging environments. The unique combination of materials in Duossal ensures even heat distribution across the surface, resulting in efficient and fast cooking.

Duossal 2.0™ is a trademark registered by Trangia and has been in production since 2017. The previous version of Duossal was available from 1994-2010. The main difference in version 2.0 is the thickness of the stainless steel layer, which was previously 0.2 mm.

What do all numbers and shortenings mean?

Trangia stove 25-4 UL/GB

The product number is more well-known than our article numbers, but what do all the numbers and shortenings mean? They represent the size, contents, and material of different variants of our Trangia stoves. This coding system has been used since the 1950s.

Why is the large storm cooker called 25 and the small one called 27? Simple, the model 25 came first. Then, stove number 27 was introduced, and as a smaller stove, the Mini Trangia 28. Before stove number 25, which was named in 1951 and initially existed in a single variant, there were other articles that came before, such as number 22, 23, and Camping set 24.

Our other materials

How to recycle?

At Trangia, we strive for sustainability and recycling in every step of the manufacturing process. Our materials come in pre-cut discs to minimize waste. After production, any waste is sorted at the factory based on quality, providing high recycling value as the material is pure from other substances. It is then delivered to industrial recyclers.

Our packaging materials are made from environmentally approved cardboard and are 100% recyclable. The consumer packaging is made from CrownBoard Craft, certified according to FSC® standards. We report our annual consumption of packaging and consumer packaging to National Packaging Association (NPA) and the Swedish Environmental Protection Agency, and we also participate in the German system “Der grune punkt” for the accountability of consumer goods packaging materials.

As an individual, when it comes to recycling we encourage you to bring your Trangia stove for metal recycling at a manned recycling center. The consumer packaging can be easily sorted at your local recycling station for household packaging. Please inquire with your municipality to find out where these stations are located.

Where does the material come from?

Our philosophy is to first search locally here in Jämtland to find raw materials and materials. Then we look within Sweden and then Europe. We consider other places in the world only if it is absolutely necessary. The aluminum, which is our main raw material, comes from European suppliers and is made up of 50% recycled aluminum. The material for our pots, pans, and windshields is delivered in pre-cut discs with various shapes and coatings. Smaller details in brass, stainless steel, and aluminum are manufactured from strips in the respective materials.

Sweden – Plastic details and purchased plastic articles. Wool & leather articles
Finland & Holland – Strips of stainless steel, aluminum & brass
Hungary & Italy – Aluminum discs & coated nonstick
Switzerland – Duossal discs
China – Fabric & EVA covers


Do Trangia products contain nickel?

Nickel is not actively added to our aluminum alloy, therefore the nickel content is not measured. Approximately 99.9% of our aluminum consists of substances that are measured and analyzed. Any nickel present would be as a very small impurity.

Duossal is composed of aluminum and stainless steel. Stainless steel does contain nickel, but it is considered to be so tightly bound that it does not pose a risk for allergies upon skin contact, similar to a regular stainless steel sink or cooking pot at home.
