Product Process
A: Yes, Cr10Ni90, Ni90Cr10 and Nichrome 90 are the same material. It is a high-performance nickel-chromium alloy containing approximately 90% nickel and 10% chromium, widely regarded as the highest-grade nichrome heating wire produced in China.
A: Cr10Ni90 resistance wire can continuously work at 1200–1400°C (depending on furnace atmosphere), making it one of the few Chinese-made alloys suitable for ultra-high temperature industrial furnaces and kilns.
A: DLX Alloy is a leading Cr10Ni90 heating wire manufacturer located in China. We supply mill certificate, factory direct pricing and worldwide export (Europe, USA, India, Southeast Asia).
A:Cr10Ni90 (Ni90Cr10): Higher nickel content → better high-temperature oxidation resistance, longer life at 1300–1400°C;Cr20Ni80 (Ni80Cr20): Cheaper, most commonly used at 1100–1200°C.For applications above 1250°C, Chinese factories and global buyers prefer Cr10Ni90.
A: Stock sizes: 1–3 days; Custom diameters: 7–15 days. Sea shipping to Europe/USA: 20–35 days; Air express: 5–8 days.
A: Yes, we provide free samples ≤ 2 meters for serious buyers. You only pay the express fee.
