Tungsten contacts’ specification types and applications:

Rivet-type tungsten contacts:
Prepared by riveting;
It can realize continuous automatic production;
Rivet-type tungsten contacts are typically used for communications relay, relay, small appliances, 3C appliances, traditional breaking switch, various types of switches and so on;

Button-type tungsten contacts:
Prepared by welding;
It can also be suitable for continuous automatic production;
Button-type tungsten contacts are commonly used in temperature breaking switch contacts, circuit breaker contacts, protection contacts and various switching contacts for conducting and breaking contact, etc;

Size range:
Contacts diameter: 0.6 ~ 10mm, diameter of line: 0.6 ~ 4.0mm, silver layer thickness: 0.15mm ~ 2.0mm.

Contacts surfaces are silver copper, silver nickel, silver, silver zinc oxide, silver cadmium oxide, silver tin oxide and silver indium tin oxide, and line materials not can be made but also be imported;
The substrate of tungsten contacts are copper nickel, copper and so on. And they can electroplate gold, silver, nickel and so on;

Rivet-type tungsten contacts and button-type tungsten contacts possess lower cost, low resistance, easier process and wide application and so on.

A distinctly separate tungsten carbide tipped saw Carbide Insert Manufacturer blade range has been developed for cutting steel pipes, tubes, sections and rails in heavy industry. That's where high mechanical stresses and operating temperatures place great demands on the saw blade. Again these saw blades can be repaired, re-tipped and re-sharpened.

A sinker is a device, usually made of tungsten, which is used to weight the line and bait to keep it on the bottom. We have talked about how to rig live bait for bottom fishing with tungsten bell sinker. Now carbide turning inserts we talk something about tungsten walking sinker

1. Insert the end of your main line through a walking sinker.

2. Tie the end of the main line to one end of a two-way barrel swivel. Tie the other end of the barrel swivel to one end of your leader.

3. Tie the other end of your 18 inches of leader line to a hook. A minnow can be hooked through the lips, a leech can be hooked under the sucker, or a night crawler can be hooked straight through, one-quarter of an inch from its tip.

Dissolving Materials
Use chemicals to dissolve the materials underneath the gold of circuit boards. CBX and StripFree products work well but do have drawbacks. CBX is a powder that is good to use in areas where not a lot of other Steel Inserts metal types are close. It will be used too quickly otherwise, reducing its cost effectiveness. StripFree should be used when an item is stainless steel based, as the solution uses an electric current to separate the gold from the board. It does require access to a car battery to work, however.

Acid Baths
Use an acid bath. While the chemicals above dissolve the materials beneath gold, acid baths are designed to dissolve the gold itself. Aqua Regia is an acid used to submerge the circuit boards. Once the boards are removed from the acid, the remaining brown, murky water will contain dissolved particles of gold. This process uses highly corrosive substances that have been made safer by the inclusion of SubZero as a replacement for nitric acid in traditional Aqua Regia. Protective clothing and precautions should still be taken when using an acid bath process.

Precipitant
Use a precipitant. Added to water, the precipitant will form a solution that will separate the gold from the acid. The separated gold, once the acid has been discarded, will resemble brown mud. At this point, no further chemicals or solutions will be needed to retrieve the gold. Washing the mud in aqua ammonia and tap water will result in a powder. The powder will then need to be melted to return the gold to its pure state.

Some scholars using the preparation of ammonium metatungstate by AMT (WO3>92.5%), soluble cobalt salts and ultra pure organic carbon as raw materials, according to the wc-6% (mass fraction) CO composition prepared tungsten cobalt mixed solution, and then the preparation of tungsten cobalt precursor cemented carbide inserts powder in spray drying tower, calcined in N2 atmosphere, finally prepared by in situ synthesis method prepared by direct carbonization of WC-CO composite powder in H2 atmosphere. For the spray conversion, the calcination process uses fixed parameters: the solution concentration is set to 60% (mass fraction), feed rate 2000ml / min, inlet temperature 240 °C, centrifugal speed 12000r / min, low temperature calcination temperature is set to 200 °C; Set the direct carbonization temperature to 800, 850 and 900 °C. In situ synthesis of WC-CO powder by direct carbonization.
