Casting alloys have good strength and are durable, light weight, rust proof, corrosion resistant, have excellent current carrying and wear properties, are easily finished by plating or with organic or inorganic finishes, have self-lubricating properties and excellent castability.
Zamak 5 has the highest impact strength of all the zinc based alloys, is approximately 10% higher in tensile strength than Zamak 3.
ZA-8 has good creep strength. It is also higher in tensile strength than all the Zamak alloys. It has superior plating and finishing characteristics.
