TECHNICAL PROPERTIES, QUALITY CONTROL GUDELINES and NORMS

The production of Zamas zinc alloys for pressure die-casting includeds three selected alloys. These are the result of in-depth experience and usage tests that place them at the forefront of the range of European products. Our laboratories constantly monitor each production base to ensure that compositions and physical properties comply with those required by the strictest international standards. Within the temperature limits set by their quality of mid-melting alloys, Zamas alloys can be used for a wide range of utilizations and their field of application continue to increase, thanks to continous research performed by specialised laboratories.

Their high level of flowability and low melting point offer noteworthy advantages in pressure die-casting with metal moulds (hot chamber casting). The high standard of cast pieces means that they are suitable for precision castings and subsequently allows pieces to be finished with extreme ease ( painting, nickel-plating, chrome-plating, etc.).
The three alloys have similar general properties, although each has been prepared to exalt either one property or a combination of properties. This can be seen by comparing the typical mechanical specifications of castings required by the standards (UNI 3718).

ZAMAS 12
Among Zamas alloys, Zamas 12 is the one with the highest degree of hardness and tensile strength.

ZAMAS 13
Zamas 13 stands out for its excellent resistance to impact and has the highest dimensional stability through time. High level of resistance to corrosion when exposed to severe weather conditions.

ZAMAS 15
Added to high degree of tensile strength of Zamas 15 are resistance to impact and dimensional stability through time similar to those obtained with the alloy Zamas 13. It also has a high level of resistance to corrosion, even in critical weather conditions.
