C51000 copper plate is a tin-phosphor bronze alloy. Its production process and product advantages are as follows:

1. Production process

Raw material processing and smelting

The raw materials of C51000 mainly include copper (Cu), tin (Sn), phosphorus (P) and other elements. Through precise batching and smelting process, the alloy composition is ensured to meet the standard (such as copper content margin, tin 4.5-5.5%, phosphorus 0.03-0.35%, etc.).

Hot processing and rolling

Hot rolling: The smelted ingot is milled and heated before hot rolling to initially form a plate or strip, and the flatness is ensured by straightening.

Cold rolling: Further cold rolling to improve surface finish and mechanical properties, while controlling tolerances (such as thickness accuracy of ±0.005mm).

Annealing and surface treatment

A multi-stage annealing process (such as annealing temperature 540-600℃) is used to eliminate internal stress and optimize material ductility. Some processes require pickling to remove the oxide layer to ensure the quality of subsequent processing.

Finishing and testing

After finishing rolling, shearing, inspection and other steps, the final product must comply with GB/T 2059-2000 and other standards, and achieve high consistency through digital technology.

Complex process characteristics

Since C51000 belongs to complex alloys such as copper-nickel-silicon, its process flow is long, the number of intermediate annealing times is high, and the energy consumption is high, but it can achieve high strength and high precision.
