Orthopedic implant metal material: medical stainless steel, titanium and titanium alloys, cobalt based alloys

With the development of the orthopedic market research orthopedic implant materials are also a growing concern. According to Lam Ching Lai Ai Ai Metal Materials Co., manager of the introduction, implantable devices now commonly used metal materials including stainless steel , titanium and titanium alloys , cobalt based alloys, these three types of materials will be a long time. Titanium and titanium alloys , domestic equipment factory for general use titanium and Ti6Al4V alloy (TC4), the United States there are 12 kinds of titanium alloy materials for implants , most commonly used in Europe and America as Ti6Al4V ELI, Ti6Al7Nb so on.
 
Lam Ching Lai Ai Ai Manager of Metal Materials Co., Ltd. , said the U.S. and Europe was more extensive use of stainless steel , the relative complexity of the Chinese market, the product has a corresponding different markets , in general, more popular titanium and titanium alloys. "From the joint application , it should be chosen according to different uses of different materials such as , for parts of the force can use high nitrogen stainless steel, it has a higher strength ; when wear-resistant materials required , you can use cobalt chromium- molybdenum alloy . "
 
Surface modification is currently one of the main development in the field of orthopedic implant materials . " The surface of the implantable device is in direct contact with the human body through the surface modification can be improved biocompatibility and reduced wear, thereby reducing the possibility of loosening of the implant to ensure long-term performance of the implant ." Lin said regular , Sandvik Bioline 316LVM for human implantation , and as for the manufacture of medical devices Bioline 1RK91, vacuum remelting former is a molybdenum-containing austenitic stainless steel with good corrosion resistance and microstructure of purity can be used in joint joint handle class femoral nail and wound class , bone plates , bone positioning pin , nail, acetabular cup ; latter is a precipitation hardening stainless steel , commonly used in bone drill , bone needles and other surgical equipment products , the strength ( after aging ) , toughness and corrosion resistance on the performance is superior. Both applications are more in the Chinese market .
 
" You can also learn from the experience of other areas, such as the experience of the application of materials development tool to develop joint implant material , the use of ceramic coatings for surface modification ." Lin Regular added.
