Excellent surface treatment White Aluminum Oxide Grit
Junda White aluminum oxide grit is a 99.5% ultra pure grade of blasting media. The purity of this media along with the variety of grit sizes available make it ideal for both traditional microdermabrasion processes as well as high-quality exfoliating creams.
Junda White aluminum oxide grit is an extremely sharp, long-lasting blasting abrasive that can be re-blasted many times. It is one of the most widely used abrasive in blast finishing and surface preparation because of its cost, longevity, and hardness. Harder than other commonly used blasting materials, white aluminum oxide grains penetrate and cut even the hardest metals and sintered carbide.

Durable hard fiber Walnut Shells Grit
Walnut shell grit is the hard fibrous product made from ground or crushed walnut shells. When used as a blasting media, walnut shell grit is extremely durable, angular and multi-faceted, yet is considered a ‘soft abrasive’. Walnut shell blasting grit is an excellent replacement for sand (free silica) to avoid inhalation health concerns.

High strength fine abrasive rutile sand
Rutile is a mineral composed primarily of titanium dioxide, TiO2. Rutile is the most common natural form of TiO2. Predominantly used as a raw material for chloride titanium dioxide pigment manufacture. Also used in titanium metal production and welding rod fluxes.It has excellent properties such as high temperature resistance, low temperature resistance, corrosion resistance, high strength, and small specific gravity.

Natural abrasive corn cobs without scratch metal parts
Corn Cobs can be used as an effective blasting media for a range of applications. Corn Cobs are a softer material similar in nature to Walnut Shells, but without the natural oils or residue. Corn Cobs contain no free silica, produces little dust, and comes from an environmentally friendly, renewable source.

The hardest blasting medium Silicon Carbide Grit
Silicon Carbide Grit
Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance, silicon carbide has many other uses besides being used as abrasives. For example, silicon carbide powder is applied to the impeller or cylinder of a water turbine by a special process. The inner wall can improve its wear resistance and prolong its service life by 1 to 2 times; the high-grade refractory material made of it has heat shock resistance, small size, light weight, high strength and good energy-saving effect. Low-grade silicon carbide (containing about 85% of SiC) is an excellent deoxidizer.

High quality cast steel shot with high wear resistance
Junda Steel Shot is manufactured by melting selected scrap in electric induction furnace. The chemical composition of molten metal is analyzed and strictly controlled by spectrometer to obtain SAE Standard specification. The molten metal is atomized and transformed into round particle and subsequently quenched and tempered in a heat treating process to obtain a product of uniform hardness and microstructure, screened by size according to SAE Standard specification.

Steel grit with SAE standard specification
Junda Steel Grit is made by crushing steel shot to angular particle subsequently tempered to different hardness for different application, screened by size according to SAE Standard specification.
Junda Steel grit is a commonly used material for processing metal work pieces. Steel grit has tight structure and uniform particle size. Treating the surface of all metal work pieces with steel grit steel shot can increase the surface pressure of metal work pieces and improve the fatigue resistance of work pieces.
The use of steel grit steel shot processing metal work piece surface, with the characteristics of fast cleaning speed, has a good rebound, internal corner and complex shape of the work piece can be uniformly quick foam cleaning, shorten the surface treatment time, improve the work efficiency, is a good surface treatment material.
