Baienwei successfully develops optimized spray forming process to produce high performance aluminum alloys.
Compared to conventional casting and powder metallurgy, spray forming process has become a revolution and trendency for producing aluminum alloys.
The following pictures are the microstructure of casting and spray forming process.
Conventional Casting Aluminum:
■ Serious macro segregation.
■ The microstructure of primary silicon and eutectic silicon is coarse, average grain size is 80-300μm.
■ Poor toughness and ductility.
■ Conventional casting process is subject to dimensions and strength.
Spray Forming Aluminum:
■ No macro segregation.
■ Grains are equiaxed (average size is 3-10μm）and distribute homogeneously.
■ Less grain boundary precipitates and high surface roughness.
■ Customized strength, up to 850 MPa.
Baienwei spray forming aluminum alloys series include have 2 main products:
Baienwei offers both spray forming aluminum alloy materials and machined products.
