We manufacture and supply a wide range of Aluminium alloy ingots used in various diecasting processes such as HPDC, GDC, LPDC, Sand casting, Investment casting etc. Aluminium Alloys ingots are widely used to make components for Automotive, Electrical, Power, Construction, Defense and various other Industries. Over the years we have established ourselves as one of the leading Aluminium alloy ingot manufacturers in India.
Our Aluminium Alloy ingots are manufactured from Virgin Aluminium Ingots, Semi Virgin Material and identified company-rejected scrap, thereby enabling us to give consistent quality regularly year after year. We are an environmentally conscious company; we use the best available pollution control equipment in our manufacturing process. The alloys that we manufacture go through systematic quality checks before it is dispatched to our valuable customers. Many of you may not be aware the quality of the alloy also depends on the type of Silicon Metal one uses. In our case, the Silicon Metal that is used in our alloys is sourced from companies that manufacture world-class Silicon metal using the latest German Technologies.

Aluminum alloy industry is an important part of the non-ferrous cast metal industry. Aluminum alloys encompass a combination of aluminum metal and other alloying elements. It supports maintaining the precise chemical specifications in the finished products.
Aluminium foundry alloys are used for aluminium castings.
Shreedhar metal’s production is based on Secondary aluminium. Consistent high metal quality is ensured using top-grade raw materials and applying best practices. Our foundry alloys are produced to meet individual customer specifications in the main alloy groups meeting specifications in accordance with BS and JIS standards.
Key features
- Excellent castability
- High and consistent metal quality
- Low level of impurities and trace elements
Product details
Alloys are produced as continuous cast or mold cast ingots. The products are stacked and strapped into bundles of various sizes. Depending on the particular production source, our foundry alloy ingots are supplied in weights of 5-6 kg, and bundle weights can range from 500-800 kg.
