Why AlSi10Mg?

Why AlSi10Mg?

AlSi10Mg is an age-hardening cast aluminum alloy with good hardness, strength and dynamic toughness. It is traditionally used as a casting alloy. Powder made from AlSi10Mg is commonly used in additive manufacturing, due to the high corrosion resistance, low density and high mechanical strength of the final components.

What is AlSi10Mg alloy?

AlSi10Mg is an aluminum alloy that combines good strength and thermal properties with low weight and flexible post-processing possibilities. For those reasons, it’s an often used material in automotive, aerospace and automation.

How much does powder bed fusion cost?

Machine cost and hourly usage rate: Machine costs are starting to decrease, but a single laser powder-bed fusion system with a typical build volume (10 by 10 by 12 inches) still costs between $400,000 and $800,000.

Can you anodize 3D printed aluminum?

Anodizing 3D-printed aluminum is technically possible but is limited because of the high percentage of silicium (10%) in the alloy (AlSi10Mg). A non-printed Aluminum part can be anodized more easily.

Is Inconel harder than steel?

Inconel 625® has a higher tensile strength than grade 304 stainless steel, and does a better job of maintaining that strength at higher operating temperatures. This is because Inconel is stronger than stainless steel at high temperatures, while being more resistant to oxidation and scaling as well.

Can you Weld Inconel?

Because of the extremely high melting point of most Inconel alloys, directly joining two Inconel workpieces (especially larger ones) is often impractical. Instead, using a welding process that combines high temperatures with a filler material is often the best way to weld Inconel alloys.

What are the disadvantages of powder bed fusion?

Disadvantages of powder bed fusion

  • Relatively slow and long print time – Powder preheating, vacuum generation, cooling off period all adds to the build time making it one of the slowest in the additive manufacturing.
  • Post-processing – Printed parts need..

What kind of material is AlSi10Mg used for?

AlSi10Mg is a typical casting alloy with good cast ing properties and is typically used for cast parts with thin walls and complex geometry. It offers good strength, hardness and dynamic properties and is therefore also used for parts subject to high loads.

Why are AlSi10Mg produced by selective laser melting?

Because of their location close to the sample border, they lack space for extensive deformation and easily cause complete fracture of the sample.

Which is better HPDC or AlSi10Mg SLM parts?

The ultimate tensile strength of the as built AlSi10Mg SLM parts is always higher than those of the HPDC in both conditions. The elongation of the as-built AlSi10Mg parts in the Z-direction is comparable to the HPDC parts, while the elongation for parts built in XY – direction is almost 2% higher.
