The melting point of aluminium metal is above 1000 Kelvin. By virtue of its strong deoxidizer power, it is less susceptible to strain ageing. Alloying with Boron can be done for increasing core hardness in constructional steels. Beryllium is a best choice for the manufacture of coil springs for watches which are antimagnetic. Chromium is a superlative material for steel alloying because it yields corrosion resistant and wear resisting alloys. Manganese is another choice in alloying of steel and resultant compound is showing excellent forging and welding properties. Nickel positively modifies the notch-impact value of structural steels. Since Sulphur is very much harmful and hazardous, it is always better to avoid it in alloying with steel. Silicon steels show superlative electromagnetic properties.
