Based in Bangkok, Thailand, Wiraphan Sheets and Plates is a trusted manufacturer and supplier of **Invar 36 sheets and plates**, offering high-performance materials for industries that require exceptional dimensional stability. With years of experience in precision alloys, Wiraphan provides Invar 36 products that adhere to strict international standards, catering to sectors like aerospace, electronics, cryogenics, and precision instrumentation. Renowned for their quality, reliability, and attentive service, Wiraphan customizes Invar 36 sheets and plates to meet the specific needs of demanding engineering applications.
**Invar 36** is a **nickel–iron alloy** made up of about **36% nickel and 64% iron**, designed for an **incredibly low coefficient of thermal expansion (CTE)**. This means it undergoes minimal dimensional changes across a broad temperature range, especially around room temperature. Invar 36 also boasts good mechanical strength, ductility, and impressive toughness at cryogenic temperatures. It remains non-magnetic at higher temperatures and can be welded, machined, and formed using standard techniques, making it a versatile choice for critical engineering tasks.
