Which alloy powder does Sagwell recommend for cutting 5000 meters of road panels?

Recently, a customer who makes professional road saw blades came to Sagwell. The customer wanted to increase the life of the saw blade and also wanted to reduce the sintering temperature as much as possible. Therefore, we recommended changing thealloy powder to improve the performance of the matrix.

After fully communicating with the customer, Our technical staff recommended the use of high tungsten carbide-based alloy powder KIN-05. Tungsten carbide is one of the hardest known metal carbides (microhardness of 2200 HV), which can effectively resist the friction and wear of sand and aggregate in concrete.

At the same time, KIN-05 also has excellent high-temperature stability. It is not easy to soften or oxidize under the high temperature generated by high-speed cutting, and maintains the stability of the matrix structure. After adding this material, the cutting life of the customer's road sheet has increased by at least 20%. You may ask when you see this, this customer also wants to lower the sintering temperature? The sintering temperature of tungsten carbide can be at least 1000℃.

Let's look at the specification. This material also contains nickel, iron, Copper, cobalt and other materials. After pre-alloying, in the temperature range of 900-950℃, the density reaches 97-98%, the hardness reaches 114.6-115HRB, and the bending resistance reaches 1350-1545Mpa.

The same level of tungsten carbide needs to be fired at at least 1000°C.

Below is the road data after improvement by our customer, what do you think?

Equipment: 10.5kw sliding table saw, 3000 rpm
Wet cutting
600mm*50mm concrete C35
Cutting speed: 2.1m/min
Cutting 300mm*50mm grinding wheel
Wear: 0.58-0.6mm/m

There are many customers who make road pavers from Sagwell. The specifications of alloy powder used to design the carcass materials are different. Please feel free to consult for more details.
