Home > Invar Bar
Welcome to Wai Nickel Alloys, your trusted partner in Naypyidaw for precision-engineered materials. We specialize in supplying the exceptional Invar Bar, a unique alloy crafted for applications where unwavering dimensional stability is absolutely critical. Our commitment is to provide local industries with reliable, high-quality materials that meet the demands of advanced engineering and technology, supporting growth and innovation right here in Myanmar.
The remarkable quality of Invar Bar stems from its specific composition of 64% iron and 36% nickel. This unique blend gives it an exceptionally low coefficient of thermal expansion, meaning it barely changes size with temperature fluctuations. This inherent stability is its key mechanical property, making it incredibly reliable in environments with significant heat variation, where other metals would expand or contract and compromise precision.
