Grain Refiners

Grain refining is a key factor in the melting and solidification processes of aluminum alloys. WHM supplies the widest range of high-quality aluminum grain refiners in the market, suitable for all aluminum wrought and foundry alloys production.

Benefits

Addition of grain refiners to molten aluminum alloys:

  • Reduces aluminum grain size

  • Improves fluidity allowing faster casting speeds

  • Enables a better homogeneity and uniformity of the structure of the alloy

  • Reduces cracking tendency during solidification

  • Enhances mechanical properties of the alloy

  • Improves quality surface of the final product

Applications

The beauty of aluminum is its use across multiple industries and verticals:

  • Transportation

  • Automotive

  • Food & Beverage

  • Energy

  • Construction

  • Military

Titanium Boron

Ti3/B1, Ti5/B1

AlTiB alloys (Aluminium Titanium Boron alloys) are the most commonly used aluminum grain refiners in aluminum alloy manufacturing. Available in different Titanium/boron ratios, the selection of ratio between Titanium and Boron will depend on several factors as desired grain size, production process conditions, and percentage of recycled aluminum used in the alloy.

Titanium Carbon

Ti3 C0.15-18

AlTiC alloys (Aluminium Titanium Carbon alloys), salts based or metal-based are the best alternative for those aluminum alloys where the addition of boron might be counterproductive as for some 5000 and 7000 series alloys and EC grade aluminum.
