Pulver av titanlegering

All You Need To Know About 3D Printing Metal Powder Suppliers

BNi-5 pulver

Pulver av titanlegering is composed of titanium mixed with other metallic elements like aluminum, vanadium, iron, and molybdenum. The powders are made by gas atomization, a process that uses high-pressure gas to turn molten alloy into fine spherical particles ideal for additive manufacturing.

Titanium alloys offer the best strength-to-weight ratio of any metallic material. They are as strong as steel but 45% lighter. When produced as fine powders, titanium alloys become suitable feedstock for advanced manufacturing techniques like selective laser sintering (SLS), electron beam melting (EBM), and binder jetting. These methods allow intricate shapes and custom designs not possible with traditional fabrication.

Titanium and its alloys stand out for their corrosion resistance in harsh environments. They withstand saltwater, acids, and chlorine much better than aluminum, magnesium, or steel alloys. Titanium is also inert and non-toxic when implanted in the human body. This biocompatibility makes it invaluable for medical devices and implants.

With advanced properties like high strength, low density, corrosion resistance, and biocompatibility, titanium alloy powders enable lighter, stronger, longer-lasting parts across aerospace, automotive, medical, chemical, marine, and consumer industries.

Titanium Alloy Powder Composition

Titanium alloy powders contain primarily titanium along with alloying elements to improve strength, hardness, and high-temperature performance. The most common titanium alloys are Ti-6Al-4V, Ti-6Al-4V ELI, and Ti-3Al-2.5V.

LegeringSammansättning
Ti-6Al-4V90% titan, 6% aluminium, 4% vanadin
Ti-6Al-4V ELI90% titanium, 6% aluminum, 4% vanadium, low interstitial impurities
Ti-3Al-2,5V95% titanium, 3% aluminum, 2.5% vanadium

Other alloying elements like iron, molybdenum, zirconium, tin, tantalum, or niobium may be present in small quantities. The composition is carefully controlled to achieve target properties after additive manufacturing.

The unique properties of titanium alloys in powder form enable advanced manufacturing, aerospace, medical, and other leading-edge applications.

The properties of printed parts depend on the additive manufacturing process as well as heat treatment after printing. For example, electron beam melting (EBM) generates finer microstructures and better mechanical properties compared to selective laser melting (SLM). Post-processing like hot isostatic pressing (HIP) can further enhance density, surface finish, dimensional accuracy, and material performance.

Some of the major application areas for titanium alloy powder include:
