4J36 Low-Expansion Alloy Plate (UNS K93600)
4J36 Low-Expansion Alloy Plate (UNS K93600) (product code PT-XHA-PRA-00033) is listed under Industrial Products & MRO > Special Alloys > Precision Alloys and supplied in Singapore by PANDA COLLECTIONS (PANDATEC PTE. LTD.), a B2B procurement partner for businesses. The iron-36 % nickel alloy has an extremely low coefficient of thermal expansion around room temperature, so parts hold their dimensions as ambient temperature changes. Prices are quoted on request.

Product description
The iron-36 % nickel alloy has an extremely low coefficient of thermal expansion around room temperature, so parts hold their dimensions as ambient temperature changes. PANDA COLLECTIONS sources 4J36 (Fe-36Ni) for buyers in Singapore and internationally for project and bulk orders. Mill test certificates to EN 10204 3.1, full heat traceability, melting route (e.g. ESR/VAR), heat-treatment condition and NDT/testing requirements are confirmed per enquiry. Prices are not listed online; every order is quoted individually based on grade, dimensions, quantity, testing and certification requirements.
