Tungsten Heavy Alloy (3H alloy)

Product Description

Tungsten Heavy Alloy Tungsten alloy has played an important role in weapon manufacturing with high density, high strength, high hardness (which is affectionately 3H alloy) and good ductility, conductivity and thermal conductivity. Industrial, aerospace and civil industry (such as the electrical industry, drilling industry, etc.) has been widely used, high proportion of tungsten alloy material has become a concern of the dual-use alloy materials.
Customized Tungsten Alloys
Tungsten heavy alloys illustrate the advantages of micro encapsulated powders. Tungsten heavy alloys generally are refractory metal which have two-phase composites consisting of W-Ni-Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added rare earth and/or other metals as Co,Mo,Cr, etc.
Tungsten heavy alloy have very high melting point and have a density twice that of steel and are more than 50% heavier than lead. Tungsten content in conventional tungsten heavy alloys varies from 90 to 98 weight percent and is the reason for their high density (between 16.5 and 19.00g/cc). Nickel, iron and/or copper serve as a metal binder matrix, which holds the brittle tungsten grains together and which makes tungsten alloys ductile and easy to machine. Nickel-iron is the most popular additive, in a ratio of 7Ni:3Fe or 8Ni:2Fe (weight ratio).
The popular processing of preparing tungsten heavy alloys includes mixing the desired amount of elemental tungsten, iron, nickel or copper powders, followed by cold pressing and liquid phase sintering to almost full density. The matrix tungsten alloy melts and takes some tungsten into solution during liquid phase processing, resulting in a micro structure through which large tungsten grains (20-60µm) are dispersed in the matrix alloy. The as-sintered material often is subjected to the mo mechanical processing by swaging and aging, which results in increased strength and hardness in the tungsten heavy alloys. The majority of current uses for tungsten heavy alloys are best satisfied with the W-Ni-Fe system. Tungsten alloys such as 93W-4.9Ni-2.lFe and 95W-4Ni-lFe represent common compositions. The addition of cobalt to a W-Ni-Fe alloy is a common approach for slight enhancement of both strength and ductility. The presence of cobalt within the tungsten alloys provides solid-solution strengthening of the binder and slightly enhanced tungsten-matrix interfacial strength. Cobalt additions of 5 to 15% of the nominal binder weight fraction arc most common. Some photos of tungsten alloys from China tungsten.

FAQ Where Is Your Factory Located?
There is a saying that "Tungsten town, looking for Luoyang". Our factory is located in Luoyang, a Midwestern city in China. A strategic position with the world's largest reserve of molybdenum and the second-highest source of tungsten globally.
Why Is Your Product So Cost-Effective?
We cut out the middlemen in the end-to-end manufacturing process. Rather than obtaining semi-finished goods from other suppliers, we obtain our raw material of APT powder directly from its source.
Do You Do Spot Quality Checks Or Full Checks?
100% full inspection. Inspectors will check the finished product one by one, to ensure they adhere to all parameters.All unqualified products are discarded.
How Do You Ensure Your Lead Time?
We have an efficient Order Management System, from material preparation to machining, and finally to a full inspection. Every stage of production is strictly monitored and controlled to give you an accurate delivery time.
Company Profile We are Luoyang Bless Tungsten Molybdenum material CO.,Ltd in China. We are the main manufacturer of tungsten and molybdenum materials,our product have been exported for many years.Located in Luoyang, Henan province, which is the number one reserve of tungsten minerals in China, we have a unique advantage in sourcing the highest quality materials.
Over the past 20 years, BLESS focused on Molybdenum and Tungsten powder process, which refining Ammonium Molybdate powder, Ammonium Tungstate powder to Molybdenum and Tungsten powder. Since 2002s, we are engaged in the production of Tungsten and Molybdenum products, such as rod, sheet , wire, crucible, target shaped products also deep process according to customized products. Our products exported to Germany, Japan, USA, Brazil, India ect and always get good feedback from them. Wide production scale and difficult process customized products are what our advantages.
One of our main strengths is our strict quality control process. We utilize SEMS technology to inspect the interior structure of every batch of raw rods. If any rods are found to have cracks or defects, they are immediately rejected. Additionally, we have our own R&D laboratory dedicated to tungsten, ensuring continuous improvement in our products.
Furthermore, we have a fully automated production line. Every step is efficiently processed by machines. This guarantees a uniform quality standard and enables us to meet our customers' lead time requirements.
As a global supplier, we strive to provide the best tungsten and molybdenum materials to our customers. With our advantageous location, strict quality control, and automated production line, we are confident in our ability to meet your needs and exceed your expectations.Whether you are in need of tungsten and molybdenum products for industrial applications or research purposes, we are here to provide you with reliable and cost-effective solutions.
