Product Description

K20-K40 Grade Tungsten Carbide Hartmetall Inserts Carbide Inserts For Aluminum



Product Description:


Aviation aluminum is a kind of aluminum alloy, known as the best product in aluminum alloy.

1.  Mechanical properties

7 series aluminum alloy is the highest hardness of all aluminum alloys, so it is suitable for the aerospace field. The hardness of 6 series aluminum alloy is medium, which can basically meet the needs of production and life.
2. The cost of 
The higher the hardness of aluminum profile, the more difficult it is to shape, so the cost of aviation aluminum profile is very high.

3. welding

Aviation aluminum profiles can not be welded, can only be connected by other methods. Ordinary construction, industrial aluminum profiles can be welded, so the application field is wider
