GNEE is a trusted supplier of Inconel 625 and Inconel 718, both high-performance alloys known for their exceptional strength. The difference between Inconel 625 and Inconel 718 lies in their performance. Inconel 625 is favored for its superior corrosion resistance in harsh environments such as marine and chemical processing. Furthermore, Inconel 625 offers better machinability than Inconel 718, making it more suitable for applications requiring high temperature and corrosion resistance. Inconel 718, on the other hand, is renowned for its exceptional strength at high temperatures, making it ideal for applications in aerospace and gas turbines that require handling extreme heat.
Regarding machinability, Inconel 625 is relatively easier to machine due to its lower strength. However, Inconel 718 performs better under high stress and high temperature conditions, typically requiring more specialized machining techniques. If strength and heat resistance are primary considerations, Inconel 718 is the better choice; while Inconel 625 is better suited for environments with high corrosion resistance requirements. GNEE offers both alloys to ensure you find the ideal material to meet your specific industry needs.

Our factory
Our nickel-based alloy products originate from a modern precision manufacturing base. The factory is equipped with fully automated vacuum induction melting (VIM), electroslag remelting (ESR), and multi-directional forging hydraulic units, ensuring that every step from melting to forming meets aerospace-grade standards. Through a digital process control system, we achieve precise control over composition purity, grain size, and mechanical properties. Each batch of products is accompanied by traceable melting reports and third-party certifications (such as DNV-GL, ABS, aerospace standards, etc.), ensuring the authenticity and reliability of performance data.
Packaging and shipping
We adopt the highest industry standards for protective packaging: all rods/plates are treated with anti-rust protection and reinforced with waterproof film and wooden crates; precision components are packaged with custom foam dividers and vacuum sealing. Through our proprietary logistics coordination system, we promise that standard specification products will be prepared and shipped within 7-15 working days after order confirmation and technical details are finalized.
