Vanadium aluminum master alloys

Vanadium aluminum master alloy is semi-finished products and can be formed in different shapes. It is a pre-alloyed mixture of alloying elements. It is also known as modifiers, hardeners, or grain refiners based on its applications. It is usually added to a melt to achieve the desired result. It is used instead of pure-metal because it is very economical and save energy and production time.

Applications of Aluminum Vanadium Master Alloys:
1. Hardeners: Used for enhancing the physical and mechanical properties of metal alloys.
2. Grain Refiners: Used for controlling the dispersion of individual crystals in metals to produce a finer and more uniform grain structure.
3. Modifiers & Special Alloys: Typically used to increase strength, ductility, and machinability.

Note: There are special requirements for chemical composition, the two sides negotiated by supply and demand.

Size and tolerance
1. Product delivery by granular particle size in the range of 0.25mm ~ 6.3mm. Allowing a small amount beyond the size range of products, but their number of delivery batch weight should not exceed 4%.
2. If the demand side of the product size has special requirements, both parties determined by supply and demand.
3. appearance quality
Product surface should be clean, it does not allow the oxide film visual evidence nitride film and other metallic and non-metallic inclusions.
4. High-density inclusions
Products should be no high-density inclusions and other foreign substances. Demand-side and specified in the contract (or purchase order) when you should be 100 %.

Packaging:

The product packaging is steel drum packaging and polybag inside. The net content per barrel is specifications of 50kg. Other packing methods may be adopted upon the agreement of both parties and indicated in the contract.
