Bearing Metals

Also known as Babbitt Metal, Britannia Metal, White-metal

• A: Highly ductile, fatigue resistant, used to take heavy loads at high speeds and for massive bearings and large con-rod bearings not subjected to shock. Also used to set knife guides for sawmills.
• A1: Special tin-based alloy for use in crushers. Used for heavy duty quarry and metallurgical crushers.
• AR: Best quality whitemetal for heavy-duty, shock-loaded conditions.
• 400: Highly ductile and corrosion resistant underwater metal.
• No.4: Lead-based lower cost alloy - used in windmills.

Other grades made to customer specification.

Casting Alloy

Spin-Casting Alloys, Jewellery Casting Alloys

Consistent high quality and the never-varying formulae of our alloys is the reason spin-casters favour our metal. Whether they make jewellery, badges, keyrings or souvenirs, and whichever alloy they use, casters can work out the optimum temperatures and other variables for their design, and then can rely on consistent results because every batch of alloy is strictly to exact formula for each grade. This can save the cost of re-working or additional finishing if metal differs from batch to batch. Our CA grade is the best-selling alloy, suitable for jewellery, or larger items, and with an excellent surface for plating, favoured by all the electro-platers!

Chrome-Plating Anodes

These are made from a superior alloy to give longer trouble-free service and have copper rod centred in shaft to optimum length. Anodes are available from 750mm to 2 metres. 

Designed in consultation with top electro-plating specialists.

Low-Melting Alloys - Fusible Alloys 

Low-melting cadmium-free Gammashield alloy is recommended for use in hospitals for casting of shields used in radiation therapy. Available in 25 kg boxes, in rounds of 65mm diameter, it has melting point of 96 degrees C.

Also, cadmium-containing alloy available to melt at 74 degrees C – suitable pipe-bending

Pewter

Northern Smelters’ pewter is lead-free.

Most grades are pure tin hardened with varying amounts of antimony and copper, and melting at approx. 235 degrees C. Different grades suit centrifugal casting or hand-casting, bulky or filigree designs. It can be electroplated, polished to a high shine, or finished with a patina. Talk to us – discuss your needs.

Our special SP grade contains a small amount of silver which gives it a slightly lighter colour, excellent surface, and melting range from 220 degrees to 230 degrees C.
