Custom Dimensions for Unique Fitting Requirements
Our non-standard copper rods cover sizes outside our standard range. Standard rods come in fixed diameters. But many applications need something different. Perhaps your terminal block has an unusual hole size. Perhaps your connector requires a specific diameter that we do not stock. Perhaps you need an odd length or a special tolerance. We solve these problems. You provide the drawings. We make the rod to your exact specifications. Our team handles every custom order with extra care. Each one is different from the last. There are no existing programs to copy. Our workers set up the CNC program fresh for each order.
Step-by-Step Setup for Custom Orders
Our process for non-standard rods follows a careful sequence. First we study your drawing. We note the diameter, length, and tolerance. We also check for any special features like chamfers or threads. Then we program the CNC machine. The program controls every cutting pass. We run a sample piece next. The sample confirms the dimensions and surface finish. We measure it carefully. If everything matches the drawing, we proceed with the full order. If not, we adjust the program and try again. This testing step prevents errors in the final production run.
Your Specifications Drive Our Process
Non-standard copper rods follow your exact drawings. The material is T2 copper. Production follows GB/T5585.1-2026. Copper purity reaches Cu≥99.90%. Total impurities stay below 0.10%. Conductivity is ≥97.3% IACS. Resistivity at 20°C stays ≤0.0177 Ω·mm²/m. Density is 8.9 g/cm³. Tensile strength ranges from 220 to 260 MPa. Yield strength exceeds 170 MPa. Hardness is 65 to 90 HV. Elongation is 17% or higher.
Where Custom Rods Are Needed
Non-standard copper rods serve applications where standard sizes do not fit. Repair and maintenance work often needs odd sizes. The original part may no longer be available. We can match the original dimensions. Custom equipment also requires special sizes. The designer may specify a unique diameter. Our rods fill this need. Research and development projects also use non-standard rods. Prototype equipment often has non-standard parts. Our customers include maintenance shops and equipment manufacturers. They value our ability to create custom rods quickly.
Order and Production Information
We start production after drawing approval. The sample piece gets reviewed with you. Full production begins after your confirmation. We deliver within one to two weeks. The minimum order is 1000 kilograms. Mixed specifications are allowed. We welcome third-party inspection. Our raw material inventory stays well-stocked. We accept USD, EUR, and CNY. Our team documents every custom setup. This helps us improve future processing.
