VM ZINC® is rolled zinc alloyed with copper and titanium to produce a material with optimum mechanical and physical characteristics for building applications, particularly with regard to mechanical resistance and creep resistance.
VM ZINC® is composed of very high quality zinc Z1 (99.995% pure zinc), as defined by the EN 1179 standard, to which titanium and copper are added:
min.
max.
Titanium
0.06%
0.20%
Copper
0.08%
1.00%
Copper increases the mechanical resistance of the alloy, making it harder and stronger.
Titanium increases creep resistance permitting greater thermal expansion and contraction, of the material without causing metal fatigue.
