Aluminium is one of the most versatile industrial metals, widely valued for its low weight, high strength, and excellent corrosion resistance. Cuprumex supplies a comprehensive range of aluminium products, covering everything from primary metal to semi-finished and fully processed materials used across construction, automotive, packaging, machinery, and engineering industries.

Primary Aluminium

We offer primary aluminium ingots, billets, and slabs, produced according to international standards. Ingots are used for remelting and casting, billets serve as the base material for extruded profiles and tubes, while slabs are rolled into sheets, coils, and plates for downstream applications.

For customers with sustainability or cost-efficiency requirements, we provide aluminium scrap in all major grades as well as secondary aluminium ingots produced from recycled material. This category offers strong economic value without compromising industrial performance.

Aluminium ingots are classified according to

Classification of Aluminium Ingots

Aluminium ingots are classified based on several international criteria that define their purity, alloy type, and physical form. The most common classifications include

:

1. Classification by Purity (Chemical Composition)

​

This is the primary way aluminium ingots are categorized. Typical purity grades include:

• High-Purity Aluminium (99.99% – 99.999%) Used in electronics, aerospace, and specialty applications.

• Primary Aluminium (99.70% – 99.80%) Standard commercial grade produced by smelters, suitable for most industrial uses.

• Secondary Aluminium (various purities) Produced from recycled scrap, purity depends on scrap grade and refining process.

Purities are usually defined by ISO, ASTM, EN, GB, or LME specifications depending on the market.
