They pride themselves on providing a reliable supply, competitive pricing, and compliance with international standards, making them a go-to partner for Nilo alloy solutions throughout Malaysia and Southeast Asia.
Nilo alloys, like Nilo 36 (Invar) and Nilo 42, are nickel-iron alloys that typically contain around 36% or 42% nickel, with the rest being iron. These alloys are celebrated for their low thermal expansion coefficient and outstanding dimensional stability across a broad temperature range. Nilo 36 boasts a tensile strength of approximately 490 MPa and a thermal expansion rate as low as 1.2 x 10⁻⁶ /°C. Nilo 42 has a slightly higher expansion rate but excels in glass-to-metal sealing applications. Both alloys are known for their good machinability, moderate strength, and stability in precision settings.

Nilo alloy bars and rods find extensive use in precision engineering sectors that demand materials with reliable thermal expansion characteristics. They are commonly used in applications like glass-to-metal and ceramic-to-metal seals in electronics, hermetic sealing, and lead frames for semiconductors. In the aerospace and instrumentation fields, Nilo alloys are utilized for components that experience temperature variations, such as precision gauges and structural supports. They are also perfect for crafting radio frequency (RF) components, thermostat rods, and laser systems. Their dependable thermal behavior makes them indispensable in scientific applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
