Zinc foundry – ZnAl
This material has very good technology and durability. Castings are made of ZnAl positively react to the coating of applied galvanic methods. The advantage of these alloys is the low cost of manufacture. Zn content in the alloy improves the mechanical properties without heat treatment.
Alloys do not only consist of aluminum (Al), and zinc (Zn), but also of copper (Cu), magnesium (Mg), manganese (Mn) and nickel (Ni), it greatly improves the strength of properties and hardness, as well as minimize the corrosion. This alloy has a relatively low probability of sparking ignition in terms of mechanical (mechanical operations). Alloy is also characterized by good weldability with the copper content of around 0.1%. Zn and Mg content of less than 6% improves the resistance to cracking.
