Industrial Zinc Product
High-purity Zinc Alloys in ZAMAK 3, 5, and 7 grades — engineered for die casting, automotive, hardware, and precision industrial components. Custom formulations available to meet specific mechanical and compositional requirements.
Product Overview
Bhatti Chemicals Industry supplies high-quality Zinc Alloys in standard ZAMAK grades (3, 5, 7) and custom formulations. ZAMAK alloys are zinc-aluminium-magnesium-copper alloys widely used in die casting due to their excellent dimensional accuracy, smooth surface finish, and strong mechanical properties.
Our Zinc Alloys are manufactured from 99.99% purity base zinc with precisely controlled alloying additions. Each batch is tested for chemical composition and mechanical properties before dispatch, ensuring consistent alloy performance for customers in the automotive, hardware, electronics, and industrial machinery sectors.
Custom zinc alloy formulations are available for buyers with specific mechanical property, dimensional, or compositional requirements — contact our team to discuss your application.

Manufacturing Process
High-purity zinc (99.99%) and precision-grade alloying elements (aluminium, magnesium, copper) are sourced from verified suppliers to ensure alloy consistency.
Alloying elements are accurately weighed and measured to meet the chemical composition targets for the specified ZAMAK grade or custom formulation.
Zinc and alloying elements are melted together under controlled temperature conditions to achieve uniform alloy formation and prevent oxidation or segregation.
Chemical composition is tested against ZAMAK grade specifications. Mechanical property testing (tensile strength, hardness) is performed on representative samples.
An optimised cooling process ensures the desired microstructure and mechanical properties are achieved in the final alloy product.
Final quality checks and documentation are completed before packaging and dispatch. Certificates of analysis are provided with every order.
Industrial Uses
ZAMAK zinc alloys are the workhorse material of precision die casting, with applications spanning automotive, consumer electronics, construction, and industrial manufacturing.
Door handles, locks, fuel systems, and under-hood brackets — zinc alloy die castings offer weight savings, strength, and excellent plating adhesion for automotive applications.
Locks, hinges, buckles, zippers, and structural hardware components that require dimensional precision, corrosion resistance, and smooth surface quality.
EMI shielding enclosures, connector housings, and device frames for electronics — ZAMAK 7 in particular suits thin-wall and complex-geometry electronic components.
Brackets, anchors, and architectural fittings where dimensional accuracy, corrosion resistance, and a consistent decorative finish are required.
Toy parts, kitchenware fittings, cosmetic packaging components, and other consumer goods where cost-effective precision casting and good surface quality are priorities.
Instrument housings, pump bodies, valve components, and precision mechanical parts for industrial equipment where dimensional stability under load is critical.
