Non-ferrous Metals
Aluminum, copper, titanium, nickel-based alloys, and special materials — including the metals not found in any standard DB.
Aluminum & Aluminum Alloys
Aluminum, with a density of 2.7 g/cm³, is the most important lightweight material. Its natural oxide layer protects against corrosion but places special demands on welding. What matters are the right alloy family, removing the oxide skin, and the appropriate filler metal.
Analyse & Artikel →Copper & Copper Alloys
Copper impresses with electrical and thermal conductivity as well as corrosion resistance. However, its high thermal conductivity is both a blessing and a curse when welding: You need lots of energy and preheating. The right copper grade and the appropriate filler metal are crucial.
Analyse & Artikel →Titanium & Titanium Alloys
Titanium combines low weight with enormous strength and corrosion resistance – the material for aerospace, medical technology, and chemical plants. When welding, titanium is merciless: above 400 °C it reacts with oxygen and nitrogen and becomes brittle. Cleanliness and complete shielding gas protection are everything.
Analyse & Artikel →Nickel & Nickel-Based Alloys
Nickel-base alloys withstand what normal steels give up on: extreme temperatures, aggressive acids, seawater. The best-known representatives are Inconel, Hastelloy, Monel, and Incoloy. When welding, they are demanding – they tend to hot cracking and require the highest cleanliness.
Analyse & Artikel →Magnesium & Magnesium Alloys
At 1.7 g/cm³, magnesium is the lightest structural metal, found in auto parts, electronics housings, and aerospace. Welding it is dangerous: magnesium burns at welding temperatures. Cleanliness, shielding gas, and respect for fire hazards are key.
Analyse & Artikel →Zinc & Zinc Alloys
Zinc is best known as corrosion protection — hot-dip galvanizing on steel. There's also zinc die casting for fittings and small parts. When welding galvanized parts, caution is needed: The vaporizing zinc fume causes metal fume fever and leaves porosity.
Analyse & Artikel →Lead & Tin – Solders and Soft Metals
Lead and tin are soft, low-melting metals used mainly as solders and for special applications like radiation shielding. When joining, soft soldering and brazing are the focus. Lead is hazardous to health and requires special caution.
Analyse & Artikel →Refractory & Specialty Metals
Refractory metals like tungsten, molybdenum, tantalum, and niobium only melt at extremely high temperatures. Together with cobalt, they fill niches: filaments, high-temperature furnaces, electronics, and wear protection. They are expensive, hard to weld, and require specialized knowledge.
