Description

Home Electrical Microwave Magnetron Ceramic / Special Ceramic Parts

1. Description:

An emerging class of permanent-magnet alloys is the iron chromes, containing iron, chromium, and cobalt. These have magnetic properties similar to the alnicos, but they are sufficiently ductile that they can be cold-rolled to thin strips, drawn into fine wires, or machined or punched into intricate shapes. They also contain less cobalt than the alnicos.

2. Feature Advantages:

1) High elasticity modulus

2) High compressive strength.

3) Anti corrosion

4) Abrasion resistance

5) Impact resistance

6) High precision

7) High stability

8) Good advanced ceramic materials

9) High welding sealing performance

10) High hardness and high density

11) Low thermal conductivity

12) Chemical inertness

13) Good wear resistance

14) High Fracture toughness

15) Good insulation performance

16) High temperature resistance
