Seven standard grades cast to IS, BS, JIS, DIN and ASTM specifications, with a spectrometer test certificate on every batch.
Our ingots are produced from sorted aluminium scrap, refined, degassed and alloyed to exact chemistry, then cast into 6–8 kg notched ingots for easy charging.
Typical ranges in weight %. Aluminium is the balance. Full certificates are issued per heat.
