Material to be joined Attributes / Comments   Common Uses
 Steel  Cast Iron  Stainless  Copper  Brass  Bronze  Nickel Alloys  Aluminium
Bronze Brazing  Manganese-Bronze x x x General purpose. Can be used in place of Tobin Bronze for many applications. NOT suitable for copper pipes carrying hot or salt water. Melting range 870-900c. Joining & repair of most ferrous and copper-based metals
Nickel Bronze (Nickel Silver) x x High-strength, good wear resistance.. Melting range 920-940c. Nickel alloys. Build-up of ferrous components, eg repairing gear teeth
Silver Brazing   45% Silver x x General purpose, high-strength. High fluidity & rapid capillary flow, Good corrosion resistance. Melting range 640-680c. Parts with close fit up. HVAC, refridgeration, marine, etc.
15% Silver
"Phos copper"
x x x x x x Joins copper-to-copper without flux, and brass-to-brass (flux required). Excellent for gap-filling where close fit-up does not exist. Melting range 645-800c. Copper pipe, plumbing fittings, hot water tanks, etc.
Joints subject to thermal expansion and service vibration.
2% Silver
"Phos copper"
x x x x x x Economic option. Joins copper to copper (with or without flux) & copper to low-zinc brass (flux required). Melting range 645-820c. Copper pipe, plumbing fittings, hot water tanks
TIG & Oxy* Welding    Steel S6 x x x x x x x Good for poor fit-up and/or where impurities such as rust and scale are present. General purpose TIG welding, or Oxy/Acetylene fusion welding, of mild steel
Stainless-Steel 316L x x x x x x x TIG welding common 300 series stainless steels 
Aluminium 5356 x x x x x x x TIG welding wide range of aluminium alloys 
*Oxy "fusion welding" of steel / stainless / aluminium is possible (although MIG &/or TIG are typically the best & most convenient / successful methods). Requires Oxy-Acetylene (not Oxy/LPG) and a suitable flux. Weldclass does not supply flux products.
