The classification of the cemented carbide

Classification of alloy

(1) tungsten carbide cobalt class

Main ingredients are tungsten carbide (WC) and the binder cobalt (Co).

The brand is by "YG" (" hard, cobalt "two word pinyin word first) and the average percentage of cobalt content.

YG8, for example, said the WCo = 8% on average, the rest for tungsten carbide tungsten carbide cobalt class.

General tungsten cobalt alloys mainly practical in: carbide cutting tools, moulds and geological mining products.

(2) cobalt tungsten titanium carbide

Main ingredients is tungsten carbide, titanium carbide (TiC) and cobalt. Its brand by the "YT" (" hard, titanium "two word pinyin word first) and the average content of titanium carbide.

YT15, for example, says TiC = 15% on average, the rest of tungsten carbide and cobalt content of cobalt tungsten titanium carbide.

(3) tungsten titanium tantalum, niobium carbide

Main ingredients are tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of cemented carbide is also called universal carbide or universal carbide.

Its brand by the "YW" (" hard "and" thousands "of two Chinese pinyin words) and serial number, such as YW1.

Shape classification

globule

Carbide ball is a high hardness of the refractory metal carbides (WC, TiC) micron grade powder as main ingredients, common cemented carbide are YG, YN, YT, YW series.

Commonly used cemented carbide balls main points: YG6 carbide ball. YG6x cemented carbide balls. YG8 cemented carbide balls. YG13 cemented carbide balls. YG20 hard alloy ball. YN6 cemented carbide balls. YN9 cemented carbide balls. YN12 cemented carbide balls. YT5 cemented carbide balls. YT15 cemented carbide balls.

clava

Carbide rods main characteristic is to have stable mechanical properties, easy to welding, high abrasion resistance and high resistance to impact.

Advantages: 1. Good abrasion resistance; 2. Good corrosion resistance; 3. High toughness; 4. Extrusion method and HIP sintering.

Purpose: cemented carbide rods is mainly suitable for drill bit, end milling cutter, reamer. It can also be used for cutting, stamping, and measuring tool. It was used in papermaking, packaging, printing, non-ferrous metal processing industry. In addition, it is widely used for machining high speed steel cutting tools, carbide milling cutter, carbide cutting tools, cutting tools of NAS, air tools, carbide drill, milling cutter core bit, high speed steel, taperd milling cutter, the metric system of milling cutter, the micro end milling cutter, hinge, electronic tools, ladder drill, metal cutting saw, double margin drill, a gun, Angle cutter, tungsten carbide rotary file, etc.

Carbide rods can not only be used for cutting and drilling tools (such as micrometers, twiste drill, drill vertical index of mining tools), also can be used as input pin, all kinds of roll wear parts and structural material to use. In addition, it can be widely used in many fields, such as mechanical, chemical, petroleum, metallurgy, electronic and defense industries.

The plate

Hard alloy plate, with good durability and impact resistance is strong, can be used in standard hardware and stamping die. Hard alloy plate is widely used in electronic industry, the motor rotor, stator, LED lead frame, EI silicon steel sheet, etc. All carbide block must be checked strictly and only those who do not have any damage, such as porosity, bubbles, cracks, etc. Can be shipped.
