ZA 27 - Zinc Aluminum
ZA-27, or zinc aluminum alloy, contains significantly more aluminum than the Zamak group of alloys. The number 27 represents the approximate percentage of aluminum.
- ZA-27 has the highest aluminum content, highest strength, highest melting point, and lowest density of the ZA group
- This zinc alloy exhibits excellent bearing properties, which allow bearings to be designed into the casting of some applications
- Its relatively high casting temperature requires the cold-chamber process
