Product Description:
Characteristics of Metal Sleeves:
- Producing Procedure, compared to zirconium products, are much less, thus shortened the production cycle of developing new products.
- High thermal conductivity and electric conductivity, and doesn’t influenced too much by outside temperature, no electricity inside sleeve.
- Won't cause spread circumstance, no noise will occur under transmission procedure.
- It has great vibration-proof quality, won’t cause dust/powder under vibration or abrade circumstances.
Conclusion:
Nickel sleeves are made under special procedure. Compared to Zirconium and Cooper materials used in traditional casting method, they have better properties and functions. Nickel Sleeves also combined the characteristics of metal sleeves: manufacture procedures are much less compared with ceramic sleeve, and it has better stability. Not like cooper sleeve (become rusted and fragile after splashing salt water), and nickel sleeves have better insertion loss value.

Feature
|
With magnetism, belong to transitional metal. High temperature tolerance (fusion point: 1455°C), anti-oxidation, stable chemical property
|
PB is alloy of cooper and tin or cooper and lead
|
Zirconium oxide is the main oxide of zirconium. Generally Zr is awhite crystal without color or smell. Hard to be melted in water, hydrochloric acid, and sulfuric acid.
|
|
Advantage
|
High heat conductivity, high electrical conductivity, non-proliferation, non-penetrating,high malleability
|
Great castability, high strength, high wear resistant ability, stable chemical property
|
High hardness, high fusion point (2715°C), high refractive index
|
|
Disadvantage
|
|
Lower fusion point (832°C), get rusted easily
|
Fragile, complex production procedure, low vibration-proof quality
