Product Introduction
Scope of inspection
Applicable materials: Suitable for various types of copper and copper alloys such as industrial pure copper, brass, bronze, white copper, beryllium copper, chromium zirconium copper, etc.
Applicable objects: including copper and copper alloy ingots, plates, bars, pipes, strips, wires, castings, forgings, weldments, fasteners, and various copper product components.
Inspection purpose: Used for copper material grade identification, incoming material acceptance, production quality control, inventory classification, spare parts replacement, and failure analysis material determination.
Inspection Item
Quantitative detection of chemical composition: Determine the content of copper, zinc, lead, tin, nickel, aluminum, iron, beryllium, chromium and other alloy elements and impurity elements in the matrix.
Microstructure inspection: Observe grain size, phase composition, casting/deformation/recrystallization structure, and determine the microstructure state.
Hardness testing: Measuring Brinell, Vickers, and Rockwell hardness to assist in distinguishing grades and heat treatment states.
Grade comparison and determination: Compare the composition, structure, and properties with the standard grade to determine the copper and copper alloy grades.
Organizational defect inspection: detecting microscopic defects such as non-metallic inclusions, segregation, porosity, cracks, and looseness.
