Astm F136 Ti-6al-4v Eli Titanium Bar

ASTM F136 Ti-6Al-4V ELI Titanium Bar and Rod are for Surgical Implants which is our main product; our company is very good at producing high-quality titanium medical bars and rods. We supply goods to our Chinese and oversea titanium surgical implant companies. We introduce high-precision grinding machines. We have developed gr5 titanium alloy and titanium alloy rods, high precision and high-performance titanium alloy rods with tensile strength greater than 1100Mpa, tolerance h6, and microstructure A3. After many clinical trials, they can adapt to high-intensity spinal movements without other adverse effects.

 

As we know, ASTM F136 Ti-6Al-4V ELI Titanium Bar and Rod have very good corrosion resistance and excellent biocompatibility. They can be used to produce all kinds of medical devices, internal bone plates, bone screws, dental implants, and prostheses or auxiliary treatment equipment implanted in the human body. Executive Standard: ASTM F136; ASTM F67,GB/T13810-2017.ISO 5832-3.

Why choose medical human implant material? This is based on its excellent mechanical properties and chemical composition and biocompatibility.  

Standard ASTM F136/ ISO5032-3 covers all the descriptions for ASTM F136 Ti-6Al-4V ELI Titanium Bar and Rod that are used by surgically implanted manufacturers.

Advantages of biomedical titanium alloy  F136 GR5 ELI Bar and Rod :

 

1. Biocompatibility: minimal biological reaction with the human body, non-toxic and non-magnetic, as a human implant, no toxic side effects to the human body.

2. Mechanical properties: high strength, and low modulus of elasticity, both to meet the mechanical requirements and similar to the natural bone modulus of the human body, can reduce the stress shielding effect, more conducive to the growth of human bone healing.

3. Corrosion resistance: titanium alloy is a biologically inert material, which has certain corrosion resistance in the human physiological environment and does not produce pollution to the human physiological environment.

4. Lightweight: the density of titanium alloy is only 56% of that of stainless steel, which significantly reduces the load on the human body after implantation.

 

The benefits of medical ASTM F136 GR5 ELI Titanium Bar and Rod for medical devices are:

1. Instruments are lightweight, and the surgical operation process can reduce the damage to blood vessels, muscles, and organs, and reduce the fatigue of doctors, and medical titanium instruments are more suitable for fine microsurgery.

2. Good corrosion resistance and non-toxic, equipment does not rust, the wound is not easy to infection, wound healing fast;

3. Medical titanium alloy which has moderate elasticity are suitable for making instruments such as pliers, tweezers, microscope, and other instruments; Medical titanium medical instruments mainly include scalpel, surgical forceps, surgical forceps, chest amplifier, suture needle, suture line, and so on.

4. the reflective properties of medical titanium are weaker when operating under shadowless lights, making it more suitable than stainless steel.

In addition, medical titanium alloy is also an important material for assisting rehabilitation devices, such as wheelchairs, crutches, splints, medical instruments, etc.

 

Packaging and Shipping

1. inner packing: plastic foam bag;

2. outer packing: plywood case with strips;

3. We ship worldwide by FedEx, DHL, UPS, TNT, etc.

First: How to control the quality of titanium medical products: ASTM F136 Ti-6Al-4V ELI titanium rods and bars for medical devices have their own special characteristics. In addition to strict control of chemical composition and mechanical properties, there are strict requirements for the material organization and internal quality of the product, which ensures the service life of the product and 100% satisfaction of the user's needs. Therefore, in the production of medical titanium rods, we control every production process in strict accordance with medical products, treating it as an important application. From the particle size of titanium sponge raw materials, ingot chemical composition, and heat treatment process to control the formation of microstructure, as well as the finished product ultrasonic testing and many other aspects of control, so the product is shipped through the national key testing center before the test to ensure the quality of the product.

Second, Suggestions on titanium material selection for special medical devices:

1. The first material I recommend to you is GR.5 ELI Titanium Bar and Rod； Our company can provide two samples for your test. If they can meet your requirements, and be proved to be different from the materials provided by other manufacturers.  Because of the different fine-tuning of the composition of the same grade, the different processing methods, and the control of the material processing organization through heat treatment and processing, we can obtain materials with the same grade but with different properties. The fatigue resistance of the material is absolutely related to the composition of the material and the metallographic organization obtained after processing. Our products are specially designed to meet this requirement.

2. What is our company’s advantage?

We can also supply GR12 alloy. GR12 is a highly alloyed titanium alloy for the production of recoilless guns and submarine tie rod antennas that are resistant to vibration and fatigue. It is mainly suitable for use at room temperature.

Compare with ASTM F136 Gr5 ELI Titanium Bar and Rod, the GR12 alloy bar and the rod is a two-phase titanium alloy with high strength at room temperature and sufficient plasticity and toughness. Its room temperature strength is 100 MPa higher than that of GR5 and its plasticity is comparable to or slightly higher than that of GR.5.The impurity interstitial elements and the metallographic organization after processing are controlled according to the requirements in the ASTM F136 Eli standard, especially the ability to control the metallographic organization in a fine equiaxial state is the key to controlling and improving the quality of our products.

Helping customers to select good titanium and use good titanium is our company's advantage.

As GR12 alloying is more complex and difficult to process, therefore, the manufacturing cost is higher and the material is more expensive. Compared to structural titanium alloys other than F136 ELI Titanium Bar and Rod, which are required for use at room temperature, GR12 is considered cheaper.

3. In addition to titanium alloy ELI Medical Titanium Bar and Rod and GR12, other titanium alloys are also available for high strength and thermal strength.
