Want to make your aluminium alloy production even better and less costly?

Grain refiner is crucial to preventing unwanted razor streaks, cracks and defects in aluminium alloys and we are proudly the leader in the development, manufacture and application process of high efficiency grain refiners on the world stage.

Our award-winning Optifine product range, developed after 20 years of research to improve operations in the casthouse, caters for clients right across the sectors. Whether you are producing chassis for aluminium electric vehicles (EV), window frames, food cans, foil or anything else, we have a product to suit you.

Optifine is now used by 42 major casthouses worldwide in the production of over three million tonnes of alloys a year.

Put your current grain refiner to the test

If you’re unsure how efficient your current grain refiner really is and to see if you could make cost savings, why not visit our designated technology test centre?

At our centre at BCAST at Brunel University London, casthouses can test-drive the effectiveness of their grain refiners using our revolutionary Opticast testing equipment. Our MQP Technology Centre, based on our test centre in Sweden, ultimately means casthouses are able to establish the consistency of the efficiency of the grain refiner they use to reduce surface blemishes, cracking and defects.
