Purpose：Observe the microstructure of ductile iron. The morphology, size, and distribution of graphite are critical to the mechanical properties of cast iron, making their assessment essential for quality control during production. Samples undergo cutting (TableCut200), mounting (FLEXPRESS fully automatic modular hot mounting machine), grinding/polishing (Alpha610), and etching with 4% nitric acid alcohol solution to observe the microstructure (MN80 metallographic microscope).

Purpose：Observe the microstructure of aluminum alloy. Aluminum alloys are widely used in aerospace, automotive, construction, and household industries due to their lightweight properties, high specific strength, corrosion resistance, and aesthetic appeal. As aluminum purity increases, its hardness decreases, making it more prone to mechanical deformation and scratches. In high-purity aluminum, grinding may cause severe deformation or abrasive embedding, posing significant challenges during sample preparation. Samples undergo cutting (TableCUT-200), cold mounting (TJ-2568), grinding/polishing (Alpha-610), and etching with Keller’s reagent to observe the microstructure (MN80).

Purpose：304 stainless steel exhibits excellent corrosion resistance and surface finish. It is widely used in various industries, including aerospace, automotive, chemical, medical, food processing, and construction, due to its outstanding performance and versatility. Metallographic testing is a crucial component of quality control in the production and processing of stainless steel. It is primarily used to examine the grain structure of samples and conduct failure analysis of components. The sample undergoes cutting (using the Beta300 Pro), mounting (with the FlexPRESS Mounting Press), and grinding/polishing (using the Alpha610 grinder polisher). It is then electrochemically etched with a 10% oxalic acidsolution before its microstructure is examined under the MN80 metallurgicalmicroscope.

As a classic copper-tin alloy, tin bronze possesses outstanding wear resistance, corrosion resistance, fatigue resistance and non-magnetic properties, as well as excellent castability and weldability. It is an indispensable key material in the industrial industry.

Cracking, delamination, or brittle fracture during stamping and bending of SPCC cold-rolled steel may not always be explained by dimensions or conventional tensile properties.

After forging, raw steel features a ferrite-pearlite matrix. Quenching and high-temperature tempering produce fine, uniform tempered sorbite, striking a perfect balance of core strength and toughness. Low-temperature nitriding forms a dense white nitride compound layer on thread surfaces with negligible heat distortion, locking in precise thread tolerance.

Driven by the industry shift toward lightweight, energy-efficient materials, 3xxx aluminum clad with 4xxx aluminum emerges as a premium industrial aluminum solution.

Aluminum busbars are core conductive components for new energy battery modules, power electronics & energy storage systems. The integrity of laser welds directly determines current-carrying performance and long-term operational reliability.
