One Of High Level Products Aluminum Wire

The production technology of vacuum melting and hot type continuous casting technology is combined to form a new type of high-performance aluminum wire rod. The aluminum wire rod produced by this technology has a unidirectional continuous columnar crystal structure, with a bright surface, dense structure and excellent plasticity. The 8 mm diameter Al-1%Si alloy wire rod can be drawn at room temperature without intermediate annealing, and the ultra-fine wire with a wire diameter of 20 μm can be directly prepared, which provides an ideal raw material for the preparation of micro filament.

1.The joint process method of aluminum wire motor includes: first using the solder and flux of ordinary copper wire motor, welding aluminum wire and copper wire lead wire, and then immersing the welded joint into the hot melt adhesive of about 100 °C ~ 120 °C, about 45 seconds ~ 70 seconds to make the hot melt adhesive and the joint fully combined, so as to isolate the joint from the outside world, strengthen the close connection of aluminum wire and copper wire, and then add a heat-resistant 130 °C ~ 170 °C heat shrinkable sleeve outside to make the joint fixed and formed; Then heat for 80 seconds ~ 100 seconds to fix the joint. The present invention uses a joint process with a colloid and a heat shrinkable sleeve, adopts the mode of heating the melt and then heating the shrinkable sleeve, which is convenient to operate, is not easy to break the wire, and can be applied to the manufacture of small aluminum wire motors.
