Tin Bronze Metallographic Sample Preparation Case

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.

Widely applied in mechanical wear-resistant parts (bearings, shaft sleeves, gears), precision elastic components, chemical anti-corrosion pipe fittings, marine equipment and non-magnetic accessories, it plays a vital role in high-end equipment, marine engineering and precision manufacturing industries.

Metallographic analysis is the core method for quality control of tin bronze products. Metallographic inspection can clearly observe grain morphology, phase distribution, component segregation and micro defects, so as to accurately judge whether the material microstructure meets industrial standards.

Standardized sample preparation and testing effectively eliminate hidden risks including part abrasion, corrosion failure and unqualified mechanical properties, providing core data support for production quality control, process optimization and service stability of tin bronze components.

Standard Metallographic Preparation Process for Tin Bronze Samples:

① Grind and remove cutting deformation layer & flatten sample surface with P400 metallographic abrasive disc;

② Fine grinding: POS disc + 9μm PD-WT polishing suspension;

③ Rough polishing: YS-JP polishing cloth + 3μm PD-WT polishing suspension;

④ Final polishing: ZN-ZP polishing cloth + SO-T401 polishing fluid.
