Conventional element detection in metal materials
/>Oxygen, nitrogen and hydrogen gas element detection, precious metal detection, heavy metal detection and detection of metal components of other types of materials.

Quality iron-based alloys such as carbon steel, stainless steel, tool steel, cast iron and other copper-based alloys pure copper, brass, cupronickel, bronze and other aluminum-based alloys modified aluminum, cast aluminum, pure aluminum and other magnesium-based alloys Nickel-based alloys such as magnesium-aluminum-zinc, magnesium-aluminum-silicon, high-temperature alloys, precision alloys and other titanium-based alloys, pure titanium, tin-based alloys such as pure tin, lead-tin alloys, lead-free solder, etc.
Aluminum alloys are available in several materials or Several types
Aluminum profile die-cast aluminum alloy
The surface quality of aluminum profiles also has defects that are difficult to overcome: warping, deformation, black lines, convex and concave lines, and white lines. Those with high level of designers and reasonable mold design and production process can avoid the above defects and make them less obvious. Inspection of defects should be carried out according to national inspection methods, that is, visual distance ~ to identify defects.
Compared with the processing methods of die-casting alloys and profiles, the equipment used is different. Its raw materials are aluminum ingots of about the purity and alloy materials, which are melted in the furnace and entered into the die-casting machine for molding. The shape of die-cast aluminum products can be designed like toys, with different shapes to facilitate connection in various directions. In addition, it has high hardness and strength, and can be mixed with zinc to form zinc-aluminum alloy.
Our company specializes in providing various aluminum alloy composition testing, grade analysis, physical property testing, mechanical property testing, metallographic analysis, anti-corrosion neutrality testing, etc. Friends who need testing are welcome to call us for consultation

Metallographic analysis is one of the important means of experimental research on metal materials. It adopts the principle of quantitative metallography and displays the metallographic phase of two-dimensional metallographic samples by grinding or thin films. Microstructure measurement and calculation are used to determine the three-dimensional morphology of the alloy structure, thereby establishing a quantitative relationship between the alloy composition, structure and properties. Applying computers to image processing has the advantages of high precision and speed, which can greatly improve work efficiency.
Testing process
Body sampling test block inlaid with rough grinding, fine grinding and polishing for corrosion observation
The first step is to determine the sample selection part and interception method
Select the sampling part and inspection surface, this process The characteristics and processing technology of the sample should be comprehensively considered, and the selected parts must be representative.
The second step is inlay.
If the size of the sample is too small or the shape is irregular, it needs to be mounted or clamped.
The third step is rough grinding of the sample.
The purpose of rough grinding is to flatten the sample and grind it into a suitable shape. General steel materials are often roughly ground on a grinder, while softer materials can be smoothed with a file.
The fourth step is to finely grind the sample.
The purpose of fine grinding is to eliminate the deep scratches left during rough grinding and prepare for polishing. General material grinding methods are divided into two types: manual grinding and mechanical grinding.
The fifth step is sample polishing.
The purpose of polishing is to remove the fine wear marks left by polishing and create a bright and traceless mirror surface. Generally divided into three types: mechanical polishing, chemical polishing and electrolytic polishing, and the most commonly used is mechanical polishing.
