Hiperco 50 optical round rod
Introduction to 1j22 material:
1J22 is a high saturation magnetic induction iron cobalt vanadium
soft magnetic alloy.
1J22 alloy has the following characteristics:
High saturation magnetic induction intensity: Among existing soft
magnetic materials, 1J22 has the highest saturation magnetic
induction intensity, reaching 2.4T. 1
High Curie point: With a Curie point of 980 ℃, it can operate at
higher temperatures where other soft magnetic materials have
completely demagnetized, maintaining good magnetic stability.
Large magnetostriction coefficient: The maximum saturation
magnetostriction coefficient is 60-100 × 10-6, which is extremely
suitable for making magnetostrictive transducers with high output
energy and high work efficiency.
The chemical composition of 1J22 mainly includes elements such as iron, cobalt, vanadium, carbon,
manganese, silicon, phosphorus, sulfur, copper, nickel, etc.
The specific ingredients are as follows:
| Fe | Co | V | C | Mn | Si | P | S | Cu | Ni |
| Excess | 49.0-51.0% | 0.80-1.80% | ≤ 0.04% | ≤ 0.30% | ≤ 0.30% | ≤ 0.020% | ≤ 0.020% | ≤ 0.20% | ≤ 0.50% |
Iron (Fe): Excess
Cobalt (Co): 49.0-51.0%
Vanadium (V): 0.80-1.80%
Carbon (C): ≤ 0.04%
Manganese (Mn): ≤ 0.30%
Silicon (Si): ≤ 0.30%
Phosphorus (P): ≤ 0.020%
Sulfur (S): ≤ 0.020%
Copper (Cu): ≤ 0.20%
Nickel (Ni): ≤ 0.50%
The precise ratio of these components ensures the high saturation
magnetic induction intensity and good mechanical properties of
1J22.
The density of 1J22 alloy is 8.20g/cm ³.
The physical properties of 1J22 alloy include:
Magnetic properties: The saturation magnetic induction intensity is
2.4T, and the Curie point is 980 ℃.

weld, making it suitable for manufacturing complex precision
components.
Wear resistance: 1J22 alloy has extremely high hardness and
excellent wear resistance, reducing the risk of wear during use.
Corrosion resistance: The chromium element in the alloy gives it
the ability to resist acid and alkali corrosion, allowing it to
maintain excellent performance in harsh environments.
