Controlled & Low Expansion Alloy Wire for the UK and Europe
Ken-Tron supplies alloy wire to customers in the UK, Europe, and worldwide, producing 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, 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. |
Data available in both inch and metric units to support UK and European standards.
Applications Include:
- Glass/ceramic to metal sealing
