Aluminum-based Functional Master Alloys

The main products of Lizhong Sitong New Materials include over 420 types, covering four major categories of functional master alloys, including grain refiners, modifiers, hardeners, and metal purifiers, as well as aerospace grade special master alloys. These products are widely used in automobiles, high-speed rail, aerospace, power appliances, food and pharmaceutical packaging and other fields.

Grain refiners
Modifiers
Hardeners
Purifiers
Grain refiners (Al-Ti-B) can refine the coarse grains of aluminum and aluminum alloys to the micrometer level, enhancing the mechanical properties and product processability of materials.
Modifiers (Al-Sr) can modify the coarse needle-like and lamellar structure in Al-Si alloy into spherical or granular shape, making the metallographic structure more compact and improving the metal's mechanical properties and wear resistance.
Hardeners can make the metals which are at high melting points, difficult to melt or easy to burn into the master alloy materials which are easier to melt and be alloyed, thereby improving metal recovery rates, reducing costs, and improving production efficiency for users.
Purifiers remove and separate impurities from molten metals through chemical reaction and physical intervention, thereby improving metal purity as well as the metal's mechanical properties, electrical conductivity, and thermal conductivity.
Aerospace Special Master Alloys

Special master alloys are manufactured through high-temperature alloying of rare metal elements such as vanadium, tantalum, molybdenum, tungsten, zirconium, hafnium, and niobium. Mainly used in fields including aerospace, high-end equipment manufacturing, biomedical care, and consumer electronics.

fluxes

Fluxes are used for refining (degassing, slag removal), calcium removal, magnesium removal, covering, and dross removal for aluminum and aluminum alloy melts. They have the characteristics of low addition amount, good refining effect, low metal loss, and low residual flux content. Main product categories: refining fluxes, calcium removal fluxes, magnesium removal fluxes, covering fluxes, and dross treatment fluxes.
