Controlled & Low Expansion Alloy Wire
Ken-tron produces Alloy Wires from materials such as Alloy 52, Alloy 42, 46, 48 and others. These alloys are used when expansion control is critical — for example in glass-to-metal seals, semiconductors, leading precision instrumentation, lighting, power generation and more.
Chemical & Mechanical Profile (Alloy 52 example)
Alloy | ASTM F30 / UNS N14052 |
Nickel | ~ 50.5 % nominal |
Iron | balance |
Manganese | ≤ 0.60 % |
Silicon | ≤ 0.30 % |
Carbon | ≤ 0.05 % |
Minor ≤ 0.10 % of aluminium, sulphur, phosphorus, chromium etc. | |
Temperature coefficient of expansion (30-450 °C) | ~ 9.6-10.1 µm/m·°C |
Up to 550 °C | ~ 10.2-10.7 µm/m·°C |
Mechanical strength | depends on temper; annealed maximum ~ 585 MPa (≈ 85 000 psi), harder tempers significantly higher. |
Applications Include:
- Glass/ceramic to metal sealing
- Semiconductor leads
