Zamak 5 Properties, Composition & Comparison with Zamak 3
Zamak 5 is the high-strength counterpart to Zamak 3. Designated ASTM AC41A (UNS Z35531), it shares the same 4% aluminum base but adds about 1% copper, and that one change raises tensile strength by…
Zamak 3 Properties, Composition & Die Casting Applications
Zamak 3 is the default zinc die casting alloy. Designated ASTM AG40A (UNS Z33520), it accounts for more than 70% of all zinc die castings in North America, and it is the grade a part gets specified…
Zinc Casting Alloys: Zamak and ZA Series Selection Guide
Zinc casting alloys split into two families: the conventional Zamak grades and the higher-aluminum ZA grades. Both pour cleanly, hold tight tolerances, and take plating well, which is why zinc…
Low Pressure Aluminum Casting: Complete LPDC Process Guide for OEM Buyers
Low pressure aluminum casting — often abbreviated as LPDC — is a process where molten aluminum is pushed upward into a permanent mold from a sealed furnace below. The driving force is low-pressure…
Aluminum Gravity Die Casting: Complete Process Guide for OEM Buyers
Aluminum gravity die casting — also called permanent mold casting — is a process where molten aluminum is poured into a reusable steel or cast iron mold. No external pressure is applied. Gravity…
Lost Foam Aluminum Casting: How It Works, Advantages, and When to Use It
Lost foam casting is a process where a foam pattern — typically expanded polystyrene (EPS) — is packed in loose, unbonded sand. When molten aluminum is poured in, the foam vaporizes and the metal…
Heat Treatment of Aluminum Castings: T4, T5, T6, T7 Process Guide with Parameters
Heat treatment is one of the most commonly misunderstood steps in aluminum casting production. Buyers often request "T6" without knowing which casting processes can actually support it — and…
Cast vs Wrought Aluminum Alloy: Key Differences, Properties, and How to Choose
When customers ask us to quote a part, one of the first questions we ask is: does this need to be cast or wrought? It sounds simple, but the answer changes everything — alloy choice, process, tooling…
How to Repair Cast Aluminum: Welding, Epoxy, and Metal Stitching Guide
Cast aluminum breaks, cracks, and corrodes — and in many cases it can be fixed without replacing the part. The right repair method depends on what type of damage you're dealing with, the alloy, the…
