Abstract: The principle of SHS is to synthesize materials in solid phase by the means of chemical reaction between components. Powder synthetic filler materials is a new technology in the manufacture of filler materials, it unites braze, diffusion welding and powder metallurgy on the base of SHS technology. One way of powder synthesis research is putting copper powder into melting Al-Si solution to make ingot after fully mixed, the other is mixing copper powder, aluminium powder and Al-Si powder completely to make powder ingot which have strength to some extent under pressure with certain temperature.

Key words: High-temperature diffusion, Plastically machining, SHS
