Performance Characteristics of GA Powder and WA Powder in Metal Injection Molding Process

Water atomized powder (WA powder)and Gas atomized powder(GA powder) are main two types powder for metal injection mold process. The performance characteristics of them can be analyzed as following:

Characteristics in metal injection molding sintering process
Ø  High green density with GA powder due to spherical shape.
Ø  Lower shrinkage during sintering than WA product
Ø  Better tolerance control possible with GA powders

Mechanical properties of gas atomized powders and water atomized powders
The use of gas atomized powder gives 10~20% improvement in tensile strength, 10~20% improvement in elongation and 4~7% improvement in hardness compared to the equivalent water atomized product.
