The production process of copper alloy mainly includes the following methods:
Smelting and casting method:
Ingredients: Weigh copper and alloy elements according to the composition requirements.
Smelting: Heat in a furnace until melted and stir evenly.
Refining: Remove impurities and adjust the composition.
Casting: Pour the melt into a mold for molding. The melting temperature, type and amount of refining agent should be determined according to the type of alloy. The required equipment includes a furnace, refining equipment, and casting mold.
Powder metallurgy method:
Powder preparation: Copper alloy powder is obtained by atomization, reduction and other methods.
Powder mixing: Add lubricants, etc. and mix evenly.
Pressing molding: Pressurize in a mold.
Sintering: Combine powder particles at high temperature. The required equipment includes powder preparation equipment, press, and sintering furnace.
Deformation processing method:
Ingot heating: Reach a suitable processing temperature.
Rolling, extrusion or stretching: Deformation processing is carried out through corresponding equipment.
Intermediate annealing: Eliminate work hardening.
Final forming: Obtain the desired shape and size. The required equipment includes heating furnace, rolling mill, extruder, and stretching machine.
