Antarctic Bear Guide: With the deepening of industrial applications, domestic metal 3D printing aluminum alloy materials have made breakthroughs.
Aluminum alloys have always occupied a very important position in the field of material manufacturing due to their light weight, strength and good chemical resistance. With the continuous in-depth development of the industry field, the demand for material properties in various industries such as aerospace and automobile manufacturing has also increased rapidly. Under the needs of a variety of applications, aluminum alloy materials with high temperature resistance, high strength and high toughness have been urgently required by the market.
In December 2021, Antarctic Bear learned that Shaanxi Xinghuaye 3D Technology has developed the AK09 series of high-temperature, high-strength and high-tough 3D printing aluminum alloy materials with independent intellectual property rights through in-depth market analysis and 3 years of dedicated efforts. And with the 3D printing equipment manufacturer Beijing Yijia three-dimensional in-depth cooperation, after many product iterations, jointly developed a special metal 3D printer for the new material, the performance indicators of the printed parts are as follows:
Room temperature performance to achieve tensile strength: 500MPa, yield strength: 420MPa, elongation: 17%.
250°C high temperature performance to achieve tensile strength: 290MPa, yield strength: 280MPa, elongation: 18%.
350 °C high temperature performance to achieve tensile strength: 200MPa, yield strength: 200MPa, elongation: 11%.
△ Room temperature, 250 °C high temperature, 350 °C tensile test report
Xinghua Company passed R&D trial production in the early stage, the material performance is stable, and has begun to produce and deliver small batches.
Antarctic Bear noted that as a domestic metal 3D printer manufacturer, Yijia Three-dimensional has continuously improved and upgraded its products, especially its large-size multi-laser multi-galvanometer metal 3D printer represented by EP-M650, which has repeatedly won bids for large orders of tens of millions of yuan. From pre-research to mass production, metal 3D printing is moving towards direct manufacturing.
