Non-sag Tungsten Wire Replaces High Carbon Steel Wire as Base Material of Diamond Wire Saw

Diamond wire saw, also known as diamond wire, refers to a cutting wire that uses electroplating process or resin bonding method to fix diamond abrasive on metal wire. It is mainly used to cut high hard and brittle materials such as single crystal silicon, polycrystalline silicon, sapphire, magnetic materials and cemented carbide, etc.

Compared with free abrasive wire saws, it has the advantages of higher processing efficiency, lower energy consumption, and better cutting quality; compared with circular saws and band saws, it can not only flexibly change the cutting direction, but also process more complex geometric shapes. However, this does not mean that the wire saw does not have any shortcomings. The current wire saw with carbon steel wire as the busbar/base material has the shortcomings of large wire diameter, high wire breakage rate and short service life. Therefore, in order to make up for the deficiencies of the existing wire saws, manufacturers began to use non-sag tungsten wire to replace high carbon steel wire as the base material of diamond wire.

For the production of diamond wire saws based on tungsten wire, researchers with the patent number CN113275659A proposed a new manufacturing method. The process is as follows: (1) Optimal black tungsten wire, which goes through pay-off → three-stage electropolishing → water washing → drying → Take up the wire to prepare silver-white metallic luster tungsten wire; (2) The tungsten wire treated in step (1) is successively paid off → secondary degreasing → pickling → impact nickel → sanding → sand fixing → heat treatment → After taking up the wire, a tungsten-based diamond wire saw with a wire diameter of 30~40um can be prepared.

Thanks to the characteristics of tungsten, the tungsten-based diamond wire saw can be much cost-effectively than before and now most enterprises are trying to use the new kind of wire despite the supply of this wire is very tight. Chinatungsten Online can supply this tungsten wire. If you have got the purchasing plan, please feel free to contact us.

Application of Non-sag Tungsten Wire

Car and motorbike lamps are one of the most important applications of non-sag tungsten wire. When used non-sag tungsten wire as filament in such bulbs, the wire can have the most effective effects for the cars and motorbikes to achieve stable light from the lamps. The application in incandescent lamps has the same effects.

Non-sag Tungsten Wire

Definition of non-sag tungsten
Non-sag tungsten is tungsten doped with the element of K (potassium) or other elements to achieve the effect of non-sag of the tungsten wire. Doping with K can form bubbles in tungsten wire, which can prevent the recrystallization of the tungsten wire. And they are also responsible for their outstanding low resistance of non-sag tungsten at high temperatures of a glowing lamp filament. About 90% of non-sag tungsten is used in incandescent lamps.

Definition of non-sag tungsten wire

Non-sag tungsten wire is applied the material of non-sag tungsten so that the tungsten wire shares the properties of non-sag tungsten. They can be less shakable when used in light sources or heating elements for the dopant material used in non-sag tungsten wire.

Non-sag Tungsten Wire-Fio de tungstênio não-sag

Non-sag tungsten wire belongs to tungsten wire. It is special for its non-sag property. Pure tungsten wire can not reach such property. Adding K+ into tungsten wire during powder mixing is to increase its unique. It is also because of this property, non sag tungsten wire is widely used to manufacture filament in motorbike, truck, etc. As for these transportation cars need to go through unsmooth road, and the lamp will up-and-down sway. With non-sag filament, the lifetime will be longer.

More information, please contact sales@chinatungsten.com.

Fio de tungstênio não-sag pertence fio de tungstênio. É especial para a sua propriedade não-sag. Fio de tungstênio puro não pode alcançar tal propriedade. Adicionando K + em fio de tungstênio durante a mistura em pó é aumentar a sua única. É também por causa desta propriedade, o fio não sag tungstênio é amplamente utilizado para a fabricação de filamentos de moto, caminhão, etc. Quanto a estes carros de transporte precisa passar por estrada unsmooth, e a lâmpada para cima e para baixo influência. Com filamento não escorre, a vida será mais longa.
