Ballantine Castings maintain the highest standards of production and quality through the utilisation of the highest quality raw materials and a company wide emphasis on excellent metallurgy controls. An unflinching commitment to continual improvement in processes and product ensures all of our customers receive excellence without concession.

Below is a range of our standard metals, metallurgy and materials. We offer other variations on demand so please get in contact with any enquiry.


Grey Iron

Grey iron is one of the most versatile and most commonly used of all irons worldwide. Grey iron offers excellent machinability and flexibility meaning it can be used for a vast range of applications.

  • Max Weight: 3,000 kg
  • Min Weight: 0.5kg
  • Grades available: GR200, GR220, GR250 (others available on demand)

Spheroidal Graphite (Ductile) Iron

Ductile iron, also known as nodular cast iron, spheroidal graphite iron and SG iron, is a type of cast iron developed to mirror the qualities of mild steel. Ductile iron has much more impact and fatigue resistance compared to grey iron due to its nodular graphite formation. Ductile iron lends itself perfectly to high integrity, complex shapes. Gear rings, ornate balustrading etc.

  • Weight: 3,000 kg
  • Min Weights: 1kg
  • Grades available: 420/12, 500/7, 400/18 (others available on demand)

Ni resist or Austenitic Irons

Developed to either provide special properties or to meet the demands of service conditions that are too severe for conventional or austempered Ductile Irons. Offers extreme corrosion resistance, dimensional accuracy and an excellent surface finish.

  • Max Weight: 2,000 kg
  • Min Weights: 5kg
  • Grades available: BS6438:1986

High Chromium Irons

Developed to provide increased abrasion resistance, wear and heat resistance.

  • Max Weight: 3,000 kg
  • Min Weight: 5kg
  • Grades available: BS4844:1986


We offer a range of aluminium grades in sand castings for both engineering and architectural applications. We have recently invested in a new aluminium melting plant to further increase our capacity for the production of aluminium castings.

  • Max Weight: 600 kg
  • Min Weight: 0.5 kg
  • Grades available: On request (mainly LM6 and LM24)


We offer a specialist service in the melting of lead. We can melt up to 3 tonnes of lead for simple weight castings for use in the offshore and oil and gas industries.
