Chuck Metals stands out as a top manufacturer and supplier of Nilo Alloy K Bars and Rods in Singapore, Pulau Ujong. They specialize in delivering high-performance nickel-iron-cobalt alloy products that are perfect for applications needing precise thermal expansion characteristics and robust sealing properties. Commonly referred to as Alloy K or ASTM F-15, this material is a favorite in the electronics and telecommunications sectors due to its remarkable compatibility with hard glasses and ceramics. Chuck Metals ensures that their Nilo Alloy K Bars and Rods are produced to strict tolerances and international standards, guaranteeing exceptional quality, dimensional stability, and reliable performance in even the most demanding industrial settings.
These Nilo Alloy K Bars and Rods are made up of about 29% nickel, 17% cobalt, and the rest iron, with carefully controlled trace elements. This unique composition gives them a thermal expansion coefficient that closely aligns with hard borosilicate glass, making them perfect for hermetic seals. They typically boast a tensile strength ranging from 450 to 620 MPa and show excellent dimensional stability, thermal shock resistance, and moderate corrosion resistance. Plus, they can be welded and machined using standard techniques, provided that proper care is taken.
