Abstract
Reinforced copper matrix composite have important in structural members the contacts of switch or relay to maximize the life of the device. Particulate metal matrix composite was fabricated from Cu and 0.1, 0.2 and 0.3% Al203. The effect of alumina content on hardness, tensile strength and electrical conductivity has been investigated. Fine dispersed particles introduced into the metal matrix have significant reinforcing effect. due to their hardness, stability and insolubility in the base metal also represent obstacles to moving of dislocation.
