Hardness Tungsten Carbide Ball Bearing Valve Seat With Abrasion Resistance
Material Selection for valve ball and seats
The three most common materials for balls and seats are Tungsten Carbide, Nickel Carbide, and Titanium Carbide.
Tungsten carbide is the industry standard and for good reason; it has proven itself over many years of service in the field. It has excellent wear properties and has a Cobalt binder, but has become slightly more expensive.
Application for tungsten carbide ball
Tungsten Carbide – A very tough and durable Ball and Seat, excellent for highly corrosive and abrasive well conditions. Tungsten Carbide is a heavy, magnetic material that is extremely hard and works well where weight is needed.
Tungsten carbide balls and valve seats have the compositions of tungsten carbide(WC) and Co or Ni or Mo additives. With high compression strength, excellent wear resistance and well shock and impact resistance, tungsten carbide balls and valve seats are widely supplied as ball-rolling element in bearing industry, pump valve spool for fluid seal, check valve for petroleum digger,industrial sprayers to regulate the flow of fertilizers or pesticides to crops.
Tungsten carbide balls can be also applied in a drastically different application, it can be employed as pen balls due to their inert chemical properties. Besides, in miniature flow control devices, such as medical instrumentation and ink-jet printing, tungsten carbide balls are also frequently used.
Widely used in where extreme hardness and wear resistance is required, such as bearings, ball screws, valves and flow meters, pen, spraying machines, pump, machinery parts, oil, hydrochloric zcid lab, hardness measuring instrument, and so high-end industry.

Q1: How long is your delivery period?
A1: It depends on specific conditions. However, it could be 10 to 15 days on average.
Q2: Do you offer samples?
A2: Yes, we do offer samples. However, buyers need to pay for the freight charge. In addition, whether samples are free or not depends on the quantity you buy.
Q3: How do you pack the products?
A3: In general, we use wood, plastic or carton boxes. We also put some soft materials inside to prevent possible damage on products.
Q4: How much advance payment do I need to make?
A4: If the products you buy are in stock, you need to make full payment; if the products are out of stock, you need to make about 50 percent of full payment and then we will start the production process. However, you still need to pay the rest of charges before we deliver the products.
