Detailed difference between automotive aluminum and die-casting aluminum.

Aluminum die-casting castings are customized by manufacturers. The heat dissipation and good appearance characteristics of aluminum alloys have already surpassed today's plastic materials. In addition to the weight of aluminum alloy die-casting castings There is no substitute for plastic.

1. Material differences

The die-casting aluminum alloy generally adopts ADC12 or ALsi9cu3. The two-car aluminum materials generally use 6063 or 6061.

2. The difference in appearance.

Die-casting aluminum is equivalent to injection molding. Die-casting aluminum can create random forms. The upper side of the die-casting aluminum street light housing is generally die-casting aluminum. The form of equal section is adopted by the aluminum material of the second car, and the deformation is small, such as the radiator of the light bulb, the aluminum profile of the window and door.

3. Thermal conductivity

The general thermal conductivity of die-cast aluminum is about 80-90W/M.K, while the thermal conductivity of automotive aluminum is about 180-190W/M.K.

4. Apply

Aluminum die casting factory direct salesGeneral use For automobiles, street lights, and now mobile phone applications are also very common. Automotive aluminum is used in downlights, ceiling lights, doors and windows, etc. used more.

The molding process of die-cast aluminum. 1. Die-casting aluminum castings die-casting 2. Coarse polishing of aluminum castings to lock mold residues 3. Fine polishing of die-casting aluminum castings.
