Types of Zinc Alloy

ZA Alloys
ZA alloys, also known as zinc-aluminum alloys, are zinc alloys that contain higher aluminum content compared to Zamak alloys.

Zinc-Copper Alloys
These alloys primarily consist of zinc and copper, with copper content ranging from a few percentage points to over 30%.

Zinc-Nickel Alloys
Zinc-nickel alloys are zinc-based alloys that contain a significant amount of nickel. These alloys provide excellent corrosion resistance, even in harsh environments.

Zinc-Tin Alloys
Zinc-tin alloys combine zinc with tin as the primary alloying element. These alloys offer improved casting properties and are often utilized in die-casting applications where high fluidity and dimensional accuracy are required.

Other Custom Alloys
There are various custom zinc alloys tailored for specific applications. These alloys can include additional elements such as lead, bismuth, or silver to impart specific properties like improved machinability or enhanced melting range.

FAQ

Q: What are the properties of zinc alloy?

A: Zinc alloys have low melting points, require relatively low heat input, do not require fluxing or protective atmospheres. Because of their high fluidity, zinc alloys can be cast in much thinner walls than other die castings alloys, and they can be die cast to tighter dimensional tolerances.

Q: What is the quality of zinc alloy?

A: Zinc Alloy Benefits
The main benefits of zinc are that it has a relatively high melting point, good corrosion resistance, superior strength-to-weight ratio, low cost compared to other metals, and other characteristics that provide manufacturers with better ways to design products such as weight optimization.

Q: What are the classification of zinc alloys?

A: There are two basic families of zinc casting alloy. The conventional or 'ZAMAK' alloys are commonly named based on their sequential development, preceded by the word alloy. These include Alloy 2, Alloy 3, Alloy 5, and Alloy 7. The most recent addition to the ZAMAK family is the new high-fluidity or 'HF' alloy.

Q: What is the maximum temperature for zinc alloy?

A: What Should Be Paid Attention To When Using Zinc Alloy? The recommended furnace temperature is 415-430 ℃ for zinc alloy. The upper limit of the die-casting temperature of thin-wall parts and complex parts can be taken, but it shall not exceed 430 ℃.

Q: What is the composition of zinc alloy?

A: It is essential that only high purity (99.99 + 0/0) zinc metal be used in the formulation of alloys. Low limits on lead, tin and cadmium ensure the long-term integrity of the alloy's strength and dimensional stability.

Q: What is the hardness of zinc alloy?

A: Until recently, optimum hardness was provided by the cold chamber alloys ZA-12 and ZA-27 whose Brinell Hardness ranges from 95 to 122 when die cast. Today, Eastern manufactures a hot chamber zinc die casting alloy called EZAC whose hardness is approximately 125 Brinell.
