Magnesium Alloy 95% Forged Heat Sink Az31b Az61 Az91d Forged Heatsink

Product DescriptionChina Factory Price Forged Magnesium Alloy Heat Sink AZ31B AZ61 AZ91DProduct Description  Heat sinks are thermally conductive components or devices that absorb and dissipate heat generated by electronic components. Heat sinks cool high-powered devices to prevent overheating. The reliability of electronic components is generally reduced by the square of an increase in temperature. For example, doubling the ambient temperature around a component renders the component 25% less reliable than at the lower temperature. Heat sinks are therefore essential in dissipating generated heat and improving component longevity.In addition, the low density, low melting point, low dynamic viscosity, low specific heat capacity, low latent heat of phase change and low affinity with iron of magnesium alloys make it have low melting energy consumption, fast filling speed, fast solidification speed, and practicality. The advantages of short die-casting cycle and long mold life are very suitable for forming and processing using modern die-casting technology to directly produce thin-walled and near-net-shaped components with complex shapes. Product NameHeatsink;Magnesium heat sink;Extruded heatsink;Heat sink extrusionMaterialAZ31, AZ61, AZ91DDetailed SizeAs per customers' designMax Aspect Ratio( Fin Height / Fin Gap)More than 20 times aspect ratio heatsink can be extruded by 800 Tons--6000 Tons extruding machines by most advanced technologyMax WidthUltra wide extruded heatsink can be made by our unique friction welding technologyStandard Mold Qty30,000+ sets standard molds in stock for your option,saving your R&D costSample ServiceSamples with differernt sizes are availabe for prototypes test within 1 weekProduction ProcessProfiles Extruding---Cutting---CNC Machining(Milling, Drilling,Tapping)---Deburring--- Cleaning--- Inspecting--PackingSurface TreatmentDegreasing,(Black) Anodizing,Sand Blasting,Painting,Chromating and Laser markingReference StandardGB/T 3190-2008,GB/T 14846-2008,ISO 2768ExperienceMore than 20 years professional manufacturing experience   ApplicationLED Lighting,Inverter,Welding Machine,Communication Device,Power Supply Equipment,Electronic Industry,Thermoelectric Coolers/Generator,IGBT/UPS Cooling Systems,etc.Detailed PhotosMagnesium alloys are well-known for being the lightest structural alloys. They are made of magnesium, the lightest structural metal, mixed with other metal elements to improve the physical properties. These elements include manganese, aluminium, zinc, silicon, copper, zirconium, and rare-earth metals.Some of magnesium's favourable properties include low specific gravity and a high strength-to-weight ratio. As a result, the material lends itself to a range of automotive, aerospace, industrial, electronic, biomedical, and commercial applications.Main CategoriesOur Advantages  Packaging & ShippingFAQQ: What characteristics make a heatsink a good one?A: High heatsink surface;Good aerodynamics;Good thermal transfer within the heatsink;Perfect flatness of the contact area;Good mounting method.

Our company uses advanced production technology and automation equipment to ensure the high quality and high stability of magnesium alloys. Our magnesium alloy rods are refined by a special process, with small grains, uniform inside and outside, low impurity content, and no peeling; the company's die-casting production line uses these magnesium alloy rods as raw materials to produce magnesium alloy bicycle frames, rims, and magnesium alloys. High-quality products such as crossbow racks.Our company has now developed a formula and process for producing high-quality magnesium alloys, which are inimitable. Magnesium alloy welding wire produced with this formula and process can realize compatible welding between different magnesium alloy materials, that is, different materials of magnesium alloy can be welded with one kind of welding wire, and have the advantages of small thermal effect zone, deep welding penetration, and no blistering. In particular, the 1.2mm magnesium alloy welding wire produced uses a one-time extrusion process to replace the original extrusion and then drawing process. Relying on the excellent technical team in the industry, the company continuously expands the application range of magnesium alloy materials through technological innovati
