Available in strip and wire
Titanium use in manufacturing has grown rapidly in recent years thanks to its material characteristics offering significant advantages over many other materials. Amongst Titanium’s key benefits are its superior resistance to corrosion, highest strength-to-density ratio, low coefficient of thermal expansion, excellent machining and fabrication and unique biocompatibility properties. Both our Titanium strip and Titanium foil range can be supplied in pancake coil, traverse wound spools and cut to length sheets. We also supply round, flat, shaped, over-braided and stranded titanium wire available in spools, coils and straightened cut lengths.
Titanium has been a known element for many years, but it is only in the last 50 years or so that its importance has truly grown. The rapid growth of the Titanium industry is due to the versatility of the metal and its unique combination of features. These features include excellent corrosion resistance, outstanding strength to weight ratios and low density. The mechanical properties of Commercially Pure Titanium grades vary considerably with small changes within the chemical composition of oxygen, nitrogen, hydrogen and carbon. These alloys exists in two crystallographic forms and its alloys can be put into one of three categories:
Pure titanium has an alpha structure. However, this transforms to a beta form as a result of being heated above 882°C. The addition of alloying elements influences this transformation. Many alloys have been developed where the beta phase is retained at room temperature. This provides a material containing alpha and beta phases. The relative amounts of these phases give rise to variations in properties such as ductility, weldability and ease of forming. Several grades whilst sharing physical and mechanical properties, have been developed with specific industry applications in mind. Whilst all Titanium grades are known for their excellent corrosion resistance, particularly in corrosive environments, with the addition of palladium to grades 7 and 11, this is further enhanced, making it ideally suited for chemical processing applications. Likewise Titanium Grade 21s, a beta alloy, was developed specifically for the aerospace sector, using combined molybdenum and niobium to raise corrosion resistance to superior levels.
Owing to its property strengths, Titanium has become a vital material across a number of industry sectors. Chemical process industries rely on outstanding corrosion resistance, consequently making Commercially Pure Titanium strip an ideal material choice. Other demanding applications within aerospace, such as static and rotating gas turbine engine components, also require a combination of corrosion and heat resistance, low weight and high strength. With a low coefficient of thermal expansion, Titanium has the ability to withstand some of the most critical and highly stressed conditions. This has made it an ideal material solution for use in civilian and military airframe structures and components.
In addition to applications within the Chemical, Aerospace and Automotive sector, these alloys have multiple applications in modern Medicine. In particular, there are a wide range of medical and dental devices including artificial implants, pacemakers and frameworks, in addition to surgical instruments. Whilst it is not completely immune to corrosion within the human body, Titanium is bacteria resistant and offers biocompatibility. Unlike other metals, tissue and bone can bond to an artificial implant. This Osseointegration phenomenon is unique to the alloy. As a result of growing medical procedures and biomedical innovation, Titanium use is expected to grow further.
