The main alloy materials for die-casting metal materials are tin, lead, zinc, aluminum, magnesium, copper, etc. Zinc and aluminum alloys are the most widely used, followed by magnesium and copper alloys. Currently, zinc, aluminum, and magnesium alloys are mainly used in the electronics industry.
Formgjuten zinklegering
The molten state of zinc alloy has very good fluidity, and the melting point is as low as 365 degrees. Various post-processing treatments can be performed, such as electroplating. Therefore, it has a wide range of uses. It was also used a lot in the mobile phone industry before, but because of its large size and poor corrosion resistance, it was gradually eliminated by Aluminiumlegeringar . Den mest använda är badrumsindustrin . Vanligt använda legeringar är 2, 3, 4, 5 och 7, och den mest använda är legering 3.}}
Formgjuten aluminiumlegering
Aluminum alloy has low density, but relatively high strength, close to or exceeding high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry, second only to steel in terms of usage. The specific weight of aluminum alloy is only about 1/3 of that of iron, so it is very important in all walks of Livet, särskilt i den lätta processen för flygplan, fartyg, bilar, elektroniska instrument osv. .
Commonly used are Al-Si-Cu series, and the common ones are ADC12 (A383), ADC10 (A380), etc. There are also Al-Si series, Al-Si-Mg series, and Al-Mg series. Another name for aluminum-titanium alloy is the addition of titanium metal to the above materials. The addition of titanium metal can Förbättra produktens mekaniska egenskaper .
Formgjuten magnesiumlegering
Magnesium alloy is an alloy composed of magnesium as the base and other elements. Its characteristics are: low density, high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, greater impact load bearing capacity than aluminum alloy, and good resistance to organic and alkali corrosion. The specific gravity of magnesium is about 2/3 of Aluminium och 1/4 järn . Därför används den i stor utsträckning i elektronisk utrustning som mobiltelefoner och kommunikationsutrustning, bildelar och medicinsk utrustning .
Den mest använda är magnesiumaluminiumlegering, följt av magnesium manganslegering och magnesium zink zirkoniumlegering . Vanliga kvaliteter som används är AZ91D, AM60B, AM50A, AS41B, etc .}
