Kyhe Tech launches sustainable titanium alloy powders using innovative DH-S technology
December 18, 2024
Kyhe Technology (Ningbo) Co Ltd, based in Ningbo, China, is a newly formed company within the titanium alloy sector focused on providing cheaper, more sustainable materials to customers in industries such as aerospace, automotive, consumer electronics, and renewable energy using advanced recycling technologies and proprietary processes.
Kyhe Tech reports that it operates under a framework of sustainability and responsible manufacturing. Its 9,800 m2 facility has ESG certification, integrating environmental, social, and governance principles into its operations. Additionally, the company is certified under the Global Recycled Standard (GRS).
By sourcing recycled titanium and minimising energy-intensive processes, the company has reported having achieved significant reductions in greenhouse gas emissions and waste generation.
DH-S titanium recycled powders
Kyhe Tech uses a dehydrogenation spheroidal (DH-S) technology for producing titanium alloy powders. Unlike conventional atomisation methods, the use of recycling and reprocessing titanium materials is said to make DH-S a more cost-effective and sustainable option. The powders produced are suitable to Additive Manufacturing, Metal Injection Moulding, and coating processes.
DH-S technology is said to offer advantages that differentiate it from traditional Electron Beam Inert Gas Atomisation (EIGA) methods. By accommodating a wide range of raw materials (e.g. titanium alloy scrap, CNC machining chips, and sponge titanium fragments), the DH-S process reduces dependency on virgin resources and significantly lowers production costs.
The powders produced are said to exhibit good mechanical properties – including high tensile strength and fatigue resistance – making them well suited to demanding applications in aerospace, automotive, and medical industries. The DH-S process achieves a reported 60% cost reduction compared to EIGA powders, enabling customers to access premium materials at lower prices. With a single-batch yield rate of approximately 95%, the process minimises material waste while maximising yield.
