The process is efficient because it produces moderate to high volume net or near-net shapes, with almost no raw material loss, economically.
Powders can be alloyed to give tensile strengths from 310 MPa (15 tonnes PSI) to 900 MPa (60 tonnes PSI) after heat treatment. Components can be manufactured to give strength over twice that of wrought mild steel if necessary.
The P/M process offer the following advantages:
Process | Unit Cost | Material Cost | Design Options | Flexibility | Volumes |
---|---|---|---|---|---|
P/M | avg. | low | greatest | avg. | med-high |
Machining | n/a | high | high | high | low |
Fineblank | avg. | low | avg. | low-avg. | high |
Metal Pressing | high | lowest | avg. | low | highest |
Forging | high | avg. | avg. | least | high |
Sand Cast | low | avg. | high | avg. | low-med |
Investment Cast | avg. | high | high | high | low-high |
Die CAst | high | low | zinc/alum/nag | high | high |
GTB Components regularly re-engineer parts never before made by the P/M process, and provide cost effective design solutions for production by powder metallurgy. This results in considerable savings to our customers and often an improvement in the performance of the product
