Optimized Spray Forming Process
Dec 01, 2016

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:

Al-Si alloys

Super high strength aluminum alloys

Baienwei offers both spray forming aluminum alloy materials and machined products.
