Chromium Zirconium Copper Bar
Shanghai Metal Corporation is a leading chromium zirconium copper bar manufacturer and supplier.
Chromium zirconium copper rod (CuCrZr) features high hardness, excellent wear resistance and high softening temperature. It maintains stable mechanical performance after long-time exposure under high temperature, with good crack resistance and high electrical conductivity. The material is widely used as welding electrode raw material. Our available grades include QCr1-0.15, QCr0.6-0.4, QCr0.5, C18150, C18200, C15000 and C18000. We produce chromium zirconium copper bars with cold drawing, peeling and precision grinding processes. Eddy current conductivity test and hardness inspection are carried out to guarantee consistent material properties. We also supply finished chromium zirconium copper electrode caps.

Packaging of Chromium Zirconium Copper Bar:
Standard Packaging
Cadmium board packaging needs to take into account protection, oxidation prevention, and toxicity control. Cadmium is a toxic heavy metal, and packaging damage can generate cadmium dust risks. Internally wrapped with vapor phase anti rust paper/anti rust film to isolate moisture and prevent oxidation, and sealed with PE vacuum bags when required. Insert 5-10 pieces of built-in desiccant (silicone desiccant) into the hard partition board (cardboard/aluminum plate) or customized EPE foam card slot. Use thick corrugated cardboard boxes or solid wood/plywood boxes externally, with a complete PE anti-seepage film lining (to prevent dust leakage), and fill the empty space inside the box with pearl cotton

Q1: What is the hardness of cadmium board and is it prone to deformation?
A: Cadmium has a very soft texture with a Mohs hardness of about 2.0, which is softer than aluminum. Thin plates are prone to bending, creasing, and scratching; Rigid support plates must be added for handling and packaging, and direct stacking and heavy pressure are not allowed.
Q2: Will cadmium plates oxidize?
A: Stable in dry air at room temperature; Under humid conditions, a light yellow/brown oxide film (cadmium oxide) will form on the surface. The oxide film will affect the surface quality, and high-purity parts need to be sealed and moisture-proof packaged.
Q3: Can cadmium plates prevent radiation?
A: Yes, it has good shielding ability against gamma rays and is commonly used for nuclear testing and radiation source shielding; Not suitable for neutron shielding. The shielding effect is positively correlated with thickness.
Q4: Can cadmium plates be cut or drilled? What are the risks?
A: Can be sawed, wire cut, or sheared; Dry grinding, dry polishing, and high-speed polishing are strictly prohibited as they can generate cadmium dust and cause cancer upon inhalation.
Q5: Can cadmium plates be welded?
A: Brazable, arc welding is not recommended. High temperatures can produce cadmium smoke, which is highly toxic and requires specialized ventilation protection and certified operation.
Q6: What treatment can be done on the surface of cadmium plates?
A: The general supply is rolled smooth surface; If oxidation prevention is required, short-term application of anti rust oil is recommended, and conventional coating is not recommended. High purity components generally do not undergo surface treatment and use sealed packaging to protect the substrate.
