Fabrication

Made to a density of 6.8 g/cm³, the component has sectional density that is kept equal within 0.08 g/cm³. The part has a minimum yield strength of 43,000 psi and typical 55,000 psi tensile strength. The process control required a high level of tool geometry control along with minimum weight and sectional density variation at compact and a consistent sinter temperature profile.

Results

Originally a die cast part that needed extensive machining, the conversation of this part to powder metallurgy resulted in:

• A 38% cost reduction
• Enhanced precision
