We also carter to needs of our esteemed customers according to their specifications. We as Company believe in quality with further scope of improvement to fulfill the needs of our esteemed customers.

We make products as our customers requirements as in non ferrous metal alloys every party has different requirements suiting them the best. We try to meet our customer needs as precisely as possible. The different alloys we manufacture are as below.

Aluminum alloys
The International Alloy Designation System is the most widely accepted naming scheme for wrought alloys. Each alloy is given a four-digit number, where the first digit indicates the major alloying elements.

  • 1000 series are essentially pure aluminium with a minimum 99% aluminium content by weight and can be work hardened.

  • 2000 series are alloyed with copper, can be precipitation hardened to strengths comparable to steel. Formerly referred to as duralumin, they were once the most common aerospace alloys, but were susceptible to stress corrosion cracking and are increasingly replaced by 7000 series in new designs.

  • 3000 series are alloyed with manganese, and can be work-hardened.

  • 4000 series are alloyed with silicon. They are also known as silumin.

  • 5000 series are alloyed with magnesium, derive most of their strength from work hardening. It is suitable for cryogenic applications and low temperature work. However is susceptible to corrosion above 60C.

  • 6000 series are alloyed with magnesium and silicon, are easy to machine, and can be precipitation hardened, but not to the high strengths that 2000, and 7000 can reach.

  • 7000 series are alloyed with zinc, and can be precipitation hardened to the highest strengths of any aluminium alloy.

  • 8000 series is a category mainly used for lithium alloys.

  • Copper Alloys/ Wirebars

  • Tin Bronze Ingots

  • Aluminum Bronze

  • Leaded Bronze

  • Brass ingots/alloys
