Inconel X750 Nickel-Based Alloy Wire GH4145
Professional supply of X750 age-hardened high-temperature alloy fine wire, diameter 0.08-3mm, with straightening and cutting customization available.
Material Overview
Inconel X750 (domestic grade GH4145) is a nickel-chromium-titanium-aluminum age-hardening superalloy that achieves excellent high-temperature strength and creep resistance through γ' phase (Ni3(Al,Ti)) precipitation hardening. This alloy delivers outstanding mechanical properties below 700°C and is widely used in high-temperature components for aircraft engines.
X750 alloy wire is produced via vacuum induction melting followed by electroslag remelting to ensure material purity and microstructural uniformity. After solution treatment and aging, the wire achieves optimal comprehensive mechanical properties.

Frequently Asked Questions (FAQ)
What is the heat treatment process for X750 alloy wire?
X750 Alloy Wire Typical Heat Treatment: Solution treatment at 980-1010°C followed by air cooling, then aging at 700-720°C for 8-10 hours followed by air cooling. The solution-treated condition facilitates machining, while the aged condition achieves optimal mechanical properties.
What's the difference between X750 and GH4169?
X750 (GH4145) is primarily strengthened by the γ' phase, with a maximum service temperature of ≤700°C; GH4169 utilizes dual-phase strengthening via both γ' and γ" phases, achieving higher strength at temperatures up to 650°C. X750 is better suited for springs and fasteners, while GH4169 is ideal for turbine disks.
Can Inconel X750 be welded?
X750 alloy is weldable, but requires post-weld aging to restore properties. We recommend ERNiCr-3 filler wire; clean the surface oxide layer before welding and perform 700°C aging after welding.
What is the minimum wire diameter available for X750 alloy wire?
X750 alloy wire features a minimum diameter of 0.08mm, meeting the manufacturing requirements for precision springs and elastic components. Wire diameter tolerance is controlled within ±0.005mm.
