Brazing process of 4047 Aluminum alloy brazing rod
4047 this aluminum-silicon soldering material is used to weld aluminum with 201 aluminum powder welding. It is a kind of brazing. It is suitable for welding aluminum with relatively high purity. The working melting point temperature is between 580-620 degrees, so It is suitable for people with certain welding experience to weld thin aluminum. Similar welding materials with a lower melting point, such as low-temperature aluminum electrode WE53 solid, have a low melting point during welding, but it is about 200 degrees lower than the melting point of 4047, making low temperature aluminum welding easier.
