Zinc Alloys


Zinc alloys have become the most widespread used castings across the world due to their durability, stability and ability to be cast into complex shapes allowing for mass manufacturing.

Their usage includes household goods, plumbing parts, locks, handles, zips, toys, fishing reels and firearms.

Zinc based alloys include Zamak (Mazak)

They are often pre-polished with belts or scurfs of 180 or 240 grit to remove any cast lines.

Splendour works well for most Zinc based Died Castings, Tripomax E if less aggression is required.

For castings with a lot of rake effect 153 and Atlas give better mop adhesion followed by Chromax with a loosefold DG buff if necessary.

Take a look at the tables below to find out more about each of them - View Table >
