Hardness And Toughness of Tungsten Carbide Cutting Tool

Details: Category: Tungsten Information; Published on Friday, 04 July 2014 18:25; Hits: 1926

Tungsten carbide is the most widely used type of high speed machining (HSM) cutting tool material, this kind of material is produced by powder metallurgy process, and consists of hard carbide particles (usually a tungsten carbide WC) and the soft metal bond. At present, there are hundreds of different composition of WC cemented carbide, where cobalt (Co) are used as the binder, nickel (Ni) and chromium (Cr) is also a common bond element. In addition, you can also add other alloying elements. Why there are so many carbide grades? Cutting tools manufacturers how to select the right cutting tool material for a certain cutting machining?

The hardness and toughness WC-Co tungsten carbide has the unique superiority in both hardness and toughness. Tungsten carbide (WC) itself has the very high hardness (more than corundum or aluminum oxide), and its hardness is rarely drop when work temperature become higher. However, it lacks enough toughness, which is essential for a cutting tool performance. In order to use the high hardness of tungsten carbide, and improve its toughness, people will use metal bond tungsten carbide together, so that the material has far more than the hardness of high speed steel, at the same time, it can withstand cutting force in most machining. In addition, it also can withstand the cutting heat generated by high speed machining.

Tungsten Alloy Fishing Sinkers 2

Details: Category: Tungsten Information; Published on Friday, 04 July 2014 18:05; Written by Sherry; Hits: 645

Tungsten alloy fishing sinkers are made by rare metal – tungsten. It is an ideal substitute of the lead fishing sinker. Tungsten heavy alloys concentrate maximum weight in the smallest possible space.

They are often used as counterweight in sporting field, such as balancing, tungsten heavy alloy fishing sinkers, golf weights, etc.

Tungsten alloy fishing sinkers are an ideal, environmentally friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard. They are harder than steel and extremely dense, tungsten being on average 30 percent smaller than its lead counterpart is.
Meanwhile, they are smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. Tungsten is also used in the production of other fishing applications, such as tungsten-carbide line cutters and tungsten powder coating for fishing lines.

Advantages of Tungsten Fishing Weights

Details: Category: Tungsten Information; Published on Friday, 04 July 2014 14:31; Hits: 652

Tungsten fishing weights are becoming more popular among fishermen for many reasons. A good percentage of tournament pros are now using tungsten 100% of the time because of its many advantages. Here are some of the positive characteristics of tungsten fishing weights.

1.Tungsten weights are smaller in size and denser in weight.

2.Tungsten produces more sound under water.

3.It has better feel on under water objects.

4.Produces a smaller bait profile in the water.

5.Does not have the toxic characteristics of lead.

In today's quickly changing fishing tackle market, there are many different brands of tungsten weights to choose from.
