PRODUCT SPECIFICATION
Modi Lastek 71
TIG welding and brazing of aluminum and its alloy
GENERAL DESCRIPTION
- The excellent fluidity and the working temperature below the melting point of most Aluminium alloys makes this rod very suitable for brazing with the oxy-acetylene flame on thin sheets and profiles of aluminium.
- Penetrates very well in the tightest lap-joints.
- Suitable for joining aluminium to copper after tinning the copper with Modi Lastek 3000P.
APPLICATIONS
- Aluminium and its alloys (less than 2 % Mg).
- Pure Al, AlMn, AlMgMn, AlMg1, AlMgSi1, AlMgSi0.5 (AA1100, 1060, 3003, 3004, 5005, 5050, 6063, 6951 aso...)
- Profile constructions, tube joining (lap-joints), window frames, carriage work.
- Remark : Anodic oxidation can darken the deposit. When this is not acceptable, use welding rod Modi Lastek 74 (or another one in function of the base metal).
