What is H62 brass?
C28000 brass strip is a brass alloy material with high plasticity and high strength. It is mainly used in the manufacturing of electronic devices, semiconductor devices, motors, wires and cables and other fields. The preparation process of C28000 brass strip mainly includes hot rolling and cold rolling. Hot rolling refers to rolling raw materials heated to an appropriate temperature through a roller mill to obtain the required thickness and shape; while cold rolling refers to rolling unheated raw materials through a roller mill, usually after multiple processes. Passes of rolling and annealing to obtain finer grains and higher strength.

FAQ
| Can C28000 brass be welded? Yes, C28000 brass can be welded and brazed using appropriate techniques and filler metals designed for copper alloys, such as silicon-bronze or brass filler rods. |
| What is the density of C28000 brass? The density of C28000 brass is approximately 8.43 grams per cubic centimeter (g/cm³), or 0.304 pounds per cubic inch (lb/in³). |
| Is C28000 brass corrosion resistant? C28000 brass offers good corrosion resistance in atmospheric, fresh water, and many mild chemical environments. However, it can be susceptible to dezincification in specific stagnant or high-chloride waters. |
| What is the difference between C28000 and C26000 brass? The main difference is copper content. C28000 brass (60% Cu) is stronger and better for hot working, while C26000 brass (70% Cu) is more ductile, has better cold formability, and higher corrosion resistance. |
| What is the melting point of C28000 brass? C28000 brass has a melting range of approximately 900 to 925 degrees Celsius (1650 to 1700 degrees Fahrenheit). |
| Does C28000 brass contain lead? Yes, but in very low amounts. The ASTM specification allows a maximum of 0.30% lead, but commercial C28000 brass is typically supplied with a much lower lead content, often below 0.07%, qualifying it as "low-lead." |
