Which is better, brass or copper? Brass and red copper exist in different forms, but because many people don't know much about them, there are often such problems, such as "brass is better or red copper is better". In different fields, brass and copper have their own advantages, and there is no better or worse. [...]
Precautions for copper storage: 1. Copper materials shall be stored in a clean and dry warehouse according to composition and brand, and shall not be stored together with acid, alkali, salt and other materials. 2. If copper materials are affected with damp during transportation, they should be dried with cloth or piled up after drying [...]
Basic introduction of copper Copper is one of the earliest metals discovered by human beings. It was used by human beings more than 3000 years ago. Copper in nature is divided into natural copper, copper oxide and copper sulfide. The reserves of natural copper and copper oxide are very small. Now more than 80% of [...]
Measures to solve discoloration in brass strip production 1. Control the acid concentration during pickling. When the oxide layer on the surface of annealed brass strip is washed away, the high acid concentration is meaningless. On the contrary, if the concentration is too high, the residual acid attached to the surface of the brass belt [...]
Why does brass strip change color during production? 1. The direct cause of brass strip discoloration is residual acid on the surface of copper strip. 2. The soft Brass Belt is easier to change color than the hard Brass Belt. Because the annealing temperature of the soft copper strip is high, it is easy to [...]
The forming process of copper bar includes drawing, heat treatment, finishing and final forming. Definition of copper rod drawing Drawing is a kind of pressure processing method to change the shape and size of the blank through the die hole and apply tensile force, and it is also a key process in the production of [...]
Brief introduction of copper bar Copper bar is a kind of solid copper bar made by extrusion or drawing. There are many kinds of copper rods, including red copper rod, brass rod, bronze rod and white copper rod. Different kinds of copper bars have different molding processes and different characteristics. The forming process of copper [...]
Solutions to common problems of brass strip: 1. Solution of brass strip discoloration (1) Control the acid concentration during pickling. When the oxide layer on the surface of annealed brass strip is washed away, the high acid concentration is meaningless. On the contrary, if the concentration is too high, the residual acid attached to the [...]
Causes of pits in brass sheet strip It is believed that many people have encountered the surface of the brass plate or the brass sheet strip, which has been peeled or dented, which makes the strip unusable, It is a headache, because once there are pits or pitting on the surface, peeling will cause the [...]
Cause of edge burr of brass strip and solving Formation of edge burr in brass strip The shearing process of brass strip consists of two stages: pressing deformation stage and shearing sliding stage. When cutting brass strip, the material stress starts from elastic and plastic deformation. When the upper cutting edge descends to contact the [...]
Characteristics of brass strip production method: 1. Cold rolling of brass strip (1) Plastic deformation. (2) The pressure in the roll gap area is high, and there is a pressure distribution, * *, up to 2700mpa. (3) At the same time, there is friction along the rolling direction and the opposite rolling direction. (4) The [...]
Production process of brass strip The production process of brass strip is divided into 6 steps. Every step in the process of operation should be carefully operated to ensure product quality. Brass strip is a very common metal element, which is mainly conductive, heat conducting and corrosion resistant equipment. There are six areas for brass [...]
The competition of refrigeration copper pipe market is fierce, so it is necessary to expand new fields and enhance the competitiveness of products. Copper prices, which had been running at high levels in 2012, continued to fall in 2013, while the processing prices of refrigerated copper tubes also showed a downward trend. With the implementation [...]
Copper pipe welding technology is the most important part, and it is an important guarantee whether the copper pipe can be successfully put into use in various industries. The position of filler metal is about 2 mm above the nozzle, and the position of filler metal must be guaranteed in the front and back of [...]
The main contents of copper pipe welding include the structure and types of copper pipe welding flame and preheating state. Welding flame structure is divided into three parts: flame core, internal flame and external flame, and the temperature is the highest at 3 mm in front of the flame core, which can reach about 3,000 [...]
