Brass has higher malleability than bronze or zinc. The relatively low melting point of brass (900 to 940 Â°C, 1652 to 1724 Â°F, depending on composition) and its flow characteristics make it a relatively easy material to cast.o enhance the machinability of brass, lead is often added in concentrations of around 2%. Since lead has a lower melting point than the other constituents of the brass, it tends to migrate towards the grain boundaries in the form of globules as it cools from casting.
Properties: The melting point of antimony is 630.74Â°C, boiling point is 1950Â°C, specific gravity is 6.691 (at 20Â°C), with a valence of 0, -3, +3, or +5. Two allotropic forms of antimony exist: the usual stable metallic form and the amorphous gray form.
