Titanium Alloy Grade 4, also known as Commercially Pure (CP) Grade 4, is the strongest of all commercially pure titanium grades. In the global industrial landscape, it occupies a unique position by bridging the gap between lower-strength pure titanium (Grades 1-3) and high-strength alloys like Grade 5 (Ti-6Al-4V). Grade 4 offers excellent corrosion resistance in highly oxidizing to mildly reducing environments, coupled with a high strength-to-weight ratio that is comparable to some stainless steels but at 40% less weight.
Currently, the global demand for Titanium Grade 4 is surging, driven primarily by the Aerospace, Medical, and Chemical Processing industries. In the medical field, its superior biocompatibility and high yield strength make it the gold standard for dental implants and surgical bone screws. In the chemical sector, it is indispensable for heat exchangers, reaction vessels, and piping systems that must withstand aggressive media like wet chlorine and organic acids.
The transition towards "Green Industry" has increased the demand for Grade 4 in renewable energy applications, particularly in desalination plants and hydrogen production components where longevity and corrosion resistance are non-negotiable.
Global enterprises are moving away from spot-buying towards long-term strategic partnerships with Chinese factories that can provide consistent quality, ASTM/ASME certification, and end-to-end traceability.
Advanced CNC machining and 3D printing (additive manufacturing) are revolutionizing how Grade 4 is utilized, allowing for complex geometries in aerospace brackets and customized medical prosthetics.

Founded in 2001, ProX Metal is a high-tech enterprise specializing in the development, production, and servicing of pure and alloy titanium materials. As a leading China Titanium Alloy Grade 4 Manufacturer, we focus on providing cost-effective, stable, and high-end titanium materials for global industrial applications.
We are ISO 9001:2015 certified and hold 14 national patents, ensuring that every rod, plate, and tube leaving our factory meets the most stringent international standards (ASTM, ASME, AMS). Our 20+ years of experience allows us to assist customers with complex custom projects, from prototype to mass production.
The application of Grade 4 Titanium varies significantly by region and specific environmental conditions. Understanding these "Localized Application Scenarios" is key to successful procurement.
In coastal regions (Middle East, SE Asia), Grade 4 is used for subsea fasteners and offshore platform components due to its immunity to seawater corrosion and biofouling.
In European and North American chemical parks, our Grade 4 plates are fabricated into high-pressure reactors and piping systems handling sulphuric and hydrochloric acids.
For global medical device hubs in Germany and the USA, we provide high-precision Grade 4 rods that are micro-machined into dental implants and internal fixation devices.
China has established the world's most complete titanium supply chain. By partnering with a factory like ProX Metal, international buyers gain several strategic advantages:
Widely used against corrosive media like chlor-alkali and sulphuric acid, ensuring safe operation.
High-strength, corrosion-resistant materials for exploration, production, and refining.
Preferred material for seawater and brackish applications due to ultimate corrosion resistance.
Extends equipment life through superior thermal conductivity and strength.
