Aluminum alloy has good specific strength and is widely used in the fields of spacecraft manufacturing, mechanical equipment, and transportation. With the increasing requirements for the development of green environmental protection and circular economy, the demand for aluminum alloys with special properties is increasing, such as high temperature resistance, high strength, and high toughness aluminum alloys, which are used in weapons, ships, aviation, aerospace, automobiles, etc. There is a wide range of needs in the industry.
However, traditional aluminum alloy materials are difficult to meet the demanding requirements of high temperature resistance and high specific strength in these fields. The development of high temperature resistant aluminum alloys that meet the high temperature service conditions has good development prospects.
In the past November, EOS launched the industry's first high-temperature and high-strength aluminum alloy suitable for 3D printing. It was too late to lament the gap. The Chinese 3D printing alloy powder technology company: SXXH has also made important breakthroughs in the same technical field. SXXH has developed a high-temperature, high-strength, and high-toughness 3D printing aluminum alloy powder with independent intellectual property rights through in-depth analysis of the market and concentrated research and development for 3 years, and has in-depth cooperation with 3D printing equipment manufacturer BJYJ 3D technology. After many products Iteratively, jointly develop special printing equipment and processes for this new type of material.
The performance indicators of the materials printed by this device are as follows:
• Room temperature performance: tensile strength 500MPa, yield strength 420MPa, elongation rate 17%;
•250℃ high temperature performance: tensile strength 290MPa, yield strength 280MPa, elongation rate 18%;
• 350℃ high temperature performance: tensile strength 200MPa, yield strength 200MPa, elongation rate 11%.
