4145 brazing aluminum sheet foil coil strip
1.The Introduction of 4145 brazing aluminum sheet foil coil strip
4145 brazing aluminum sheet foil coil strip is a heat-treatable aluminum alloy with good corrosion resistance and good welding performance,
it can be used as a welding filler wire and as a filler metal. It is compatible with 2xox series aluminum alloys and aluminum/aluminum copper,or when aluminum/aluminum-copper-silicon castings are used together, the sensitivity of welding streaks is extremely low.
In addition, as a deformed aluminum alloy, it can withstand pressure processing and has higher mechanical properties than as-cast. It can be processed into various shapes and specifications of aluminum alloy materials. Mainly used in the manufacture of aviation equipment, daily necessities, doors and windows for construction, etc.
