How to make carbide strips?

Cemented carbide strips are mainly made by mixing WC tungsten carbide and Co cobalt powder by metallurgy, milling, pressing, sintering. The main alloy composition is WC and Co. WC in cemented carbide strips for different purposes It is not consistent with the composition content of Co, and is widely used.

One of the many materials of cemented carbide strips, which is named for its rectangular plate (or square), also known as cemented carbide strips.

Process flow

Milling → Formulation according to application requirements → Wet grinding → Mixing → Crushing → Drying → Screening → After adding the molding agent → Redrying → Screening to obtain the mixture → Granulation → Pressing → Forming → Low-pressure sintering → Forming (blank ) → Flaw inspection → Packaging → Storage.

Performance characteristics

Cemented carbide strips have excellent hardness, high hardness, good wear resistance, high elastic modulus, high compressive strength, good chemical stability (acid resistance, alkali resistance, high-temperature oxidation), low impact toughness, and expansion coefficient Low, thermal conductivity and electrical conductivity are similar to iron and its alloys.

How to buy carbide strips?

The tungsten carbide strips are generally purchased from these aspects:

  1. The compactness of the cemented carbide strips;
  2. Abrasion resistance of cemented carbide strips;
  3. The impact resistance of the carbide strips;

UKO’s hard alloy strips use cold isostatic pressing and low-pressure sintering technology to ensure that the strips are free of trachoma and pores, are not easy to crack during cutting, and have good wear resistance and strong impact resistance.

What is the use of carbide strips?

Carbide strips are mainly composed of WC tungsten carbide and Co cobalt powder mixed by metallurgical methods through powdering, ball milling, pressing, and sintering. The main alloy components are WC and Co. The content of ingredients is not consistent with that of Co, which makes it widely used. One of the many materials of cemented carbide strip is named after its rectangular bar shape, also known as cemented carbide strip bar.

Carbide strip performance:

Carbide strips have excellent warp hardness, high hardness, good wear resistance, high elastic modulus, high internal compressive strength, good chemical stability (acid resistance, alkali, high temperature oxidation), low impact toughness, expansion The coefficient is low, and the characteristics of thermal conductivity and electrical conductivity are similar to those of iron and its alloys.

Carbide strip application range:

Carbide strips have the characteristics of high red hardness, good weldability, high hardness, and high wear resistance. They are mainly used in the production of woodworking reversible knives, MDF, gray cast iron, non-ferrous metal materials, chilled cast iron, hardened steel, PCB, brake material. When using it, you should select the hard alloy strip with suitable material according to the application.
