What Is Zamak?Zamak Casting & Alloy Guide

1.What Is ZAMAK? The Ultimate Guide to Zinc Die Casting Alloys | Welleshaft

ZAMAK, also called ZAMAC, is a long-used family of zinc alloys that changed high-pressure die casting when it came on the scene in the 1920s. Here at Welleshaft, your go-to zinc die cast manufacturer, we work hands-on with zamak casting across industries needing tough parts made to last.

2.What Is ZAMAK (or ZAMAC)?

It stands for zinc, aluminum, magnesium, and copper—based on their German names. That’s why it ends with a ‘K’ instead of a ‘C.’ This zinc alloy stays strong under pressure and pours clean in molds, making it a top pick in die casting.

Alloy Composition Table

Alloy Type	Zinc	Aluminum	Magnesium	Copper	Notable Properties
ZAMAK 3	95%	4%	0.03%	0.02%	Balanced flow and strength
ZAMAK 5	94%	4%	0.03%	1%	Stronger; handles corrosion well in plumbing
ZAMAK 2	96%	4%	0.03%	3%	Hard and wear-resistant; works hot
ZAMAK 12	89%	10%	0.05%	1%	Great for stiff parts
EZAC	Varies	Higher	Varies	Varies	Better at creep; good in heated gear

3.History of ZAMAK in Die Casting

Before it came along, factories tossed cheap metals together and called it good. These ‘pot metals’ melted easily but cracked and warped under stress. That all shifted when this zinc alloy gave makers a better way. Today, it’s still widely used—from structural anchors to parts made with die casting machines.”

4.Why Choose ZAMAK for Die Casting?

（1）Strong But Light

Compared to plastic and softer metals, these parts hold their shape while staying lightweight. Our 5 vs 3 tensile strength study shows where each works best.

（2）Gets the Shape Right

Casting zamak means tight edges, less waste, and no need for much cutting after. It’s all about getting the form right from the start.

（3）Takes Paint Well

Whether you need smooth paint, chrome plating, or a tough powder coat, zamak alloys are easy to finish.

（4）Keeps Going

We’ve seen molds for zamak metal last past a million shots. That saves time and cuts cost for big orders.

5.Common ZAMAK Alloys at Welleshaft

1. Good all-around and easy to cast.
2. Better suited for weathered jobs like plumbing. Learn more about Type 5’s corrosion resistance in plumbing fixtures.
3. Harder and rougher; tough enough for wear.
4. Best where stiffness counts.
5. Stands up under heat and time. See our post: ezac alloy vs zamak5 creep resistance in die-casting.

6.Pick the Right Zinc Alloy for the Job

We often help folks compare zamak3 vs zamak5 die casting industry comparison for new builds. Use 3 when you need form and flow; go with 5 when you need muscle.

1. Casting Method Matters

2. Cast hot in chamber setups.

3. ZA alloys: Need cold chamber setups

At Welleshaft, we run zinc die casting machines for zamak metal factory use to keep your project moving.

8.People Also Ask

（1）What’s in ZAMAK exactly?

A: It’s mostly zinc with aluminum, copper, and a bit of magnesium. See the full alloy composition breakdown for zinc-aluminum-magnesium-copper blends.

（2）Is 5 stronger than 3?

A: Yep. The added copper in Type 5 boosts its strength. See how it stacks up in our 5 vs 3 tensile strength study.

（3）Will my mold last long?

A: Sure will. We’ve seen zinc die casting mold setups run clean for over a million shots.

（4）Can I coat or paint ZAMAK parts?

A: No problem. This metal works great with paint, chrome, or powder coats.
