Here at Pace, we have been producing Zinc-Aluminum (ZA) alloys for so long, hardly anyone remembers how the company even got started. We rounded up some of our smartest associates and picked their brains to learn more about ZA alloys. Here is what we do know.
Developed in the late 1960s and early 1970s, ZA alloys served to fill a gap in performance characteristics between zinc alloys and aluminum alloys. There are three alloys in this family; ZA-8, ZA-12 and ZA-27. The numbers in the alloy names are the approximate percentages of aluminum in the alloy. As a comparison, the nominal amount of aluminum in standard zinc alloys is 4%.
B&C Die Cast was founded in 1984 as a family-owned and operated business. The company built a reputation as a service, product and quality leader in the industry and, in 1998, became part of the Pace family. The B&C division has been producing ZA alloys for 32 years now, which provide significant benefits to the Pace customers.
The benefits of ZA alloys are vast and include:
• Improved strength
• Improved creep resistance
• Improved hardness
• Improved bearing and wear characteristics
• Lower densities than zinc alloys
We are proud to produce a product with such considerable benefits to our customers. Our B&C division produces castings using the ZA-8 alloy in a hot chamber die casting process. In addition to those benefits listed above, this process saves our customers money by providing a longer die-life — compared to dies running with aluminum alloys. Another financial benefit is that dies can also be interchanged with ZA-12 and ZA-27 alloys, without the need to purchase new dies. In addition to being affordable, we have faster cycle times than standard zinc die casting, making Pace more competitive than other companies.
The B&C division specializes 100% in zinc die castings. B&C also offers in-house machining capabilities and assembly to provide a variety of options to our customers. At Pace, we are committed to providing our customers with the highest-quality products to meet their needs in affordable and convenient ways. ZA alloys are just one way that we are making that happen.
