Zamac is an alloy of Zinc, Aluminum, Magnesium and Copper, widely used in injection and centrifugal processes for the manufacture of hardware, jewelry, costume jewelry, automotive sector and coating of industrial equipment.
These alloys are highly sensitive to impurities, especially tin, lead, and cadmium. For this reason, at Conalsol we exclusively use 99.995% pure Special High Grade Zinc, along with pure aluminum and magnesium, and electrolytic copper.
Aluminum improves mechanical properties and hardness, as well as increasing fluidity. Copper contributes to greater tensile strength and corrosion resistance. Magnesium, although in small proportions (0.1% to 0.15%), provides significant stability and inhibits intergranular corrosion.
| Alloy | Melting point | Typical application |
|---|---|---|
| Zamac 410 (Zamac 5) | 380–386°C | Injection – high resistance |
| Zamac 400 (Zamac 3) | 381–387°C | Injection – general use |
| Zamac 430 (Zamac 2) | 379–390°C | Centrifugation |
| Zamac 431 | 379–390°C | Centrifugation |
| Zamac 331 | 379–390°C | Centrifugation |
The purity of the raw materials is critical. The use of 99.995% SHG Zinc guarantees the absence of impurities that could compromise the quality of the parts.
Alloys optimized for injection and centrifugation with maximum purity.
Presentations adapted to each production process and volume of operation.
Check availability for industrial volumes and custom compositions.
Welding is part of the electrical and thermal performance of the complete system.
When the alloy is aligned with the production process, repeatability is improved, thermal control is optimized, and operational variability is reduced.
The injection molding grades (Zamac 3, Zamac 5) are optimized for high flowability and pressure mold filling. The spin molding grades (Zamac 2, 431, 331) have compositions tailored for lower-pressure processes with greater dimensional control.
Zamac alloys are extremely sensitive to impurities such as tin, lead, and cadmium, which can cause intergranular corrosion and embrittlement. The use of 99.995% pure zinc alloys eliminates this risk.
Yes. Its excellent surface finish makes it ideal for chrome plating, nickel plating, and other electrochemical baths used in hardware, jewelry, and costume jewelry.
Yes. We can adjust the composition to meet the specific requirements of your process. Please consult with engineering.
We support the selection of alloys according to technical requirements and actual application.
