Form
Zinc alloys are manufactured in ingots weighing 12 kg and 8 kg.
Ingot surface is clean, free from precipitated foreign matters, riser heads or floods.
The zinc alloy ingot
The ingot is of the following dimensions: length 460 mm, width 150 mm, thickness 35 mm
Packing
Zinc alloys are delivered without packing in packages consisting of 60 ingots tightened with a steel belts.
Depending on the alloy the weight of the package varies from 500 to 1000 kg.
Palletization of the zinc alloys or stretch foil wrapping is available upon the request.
