The aluminum tube is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity under annealing, just quenching and hot state, and has good spot welding weldability. The aluminum tube has a tendency to form intergranular cracks when gas welding and argon arc welding are used; The machinability of the aluminum tube is still good after quenching and cold work hardening, but it is not good in the annealed state. The corrosion resistance is not high, and anodic oxidation treatment and painting methods are often used to improve the corrosion resistance. It can also be used as a mold material.
A:Copper tubes, also known as copper tubes, are pressed and drawn seamless tubes.
Higher incidence of cooling system trouble in older vehicles Vehicles five years and older are prime candidates for cooling system troubles, troubles that could strike when least expected. Experts report that cooling system service is most frequent on vehicles with more than 100000 km. However, Experts note that the km on a vehicle is not as big a factor in the maintenance of a cooling system as is the vehicle’s age.
A radiator is the part of the engine cooling system that excess combustion heat is lost to atmosphere by means of forced convection using a circulating liquid such as water or water/glycol to affect heat transfer.
The radiator is an important part for the cooling of the car engine, usually installed in the vehicle Front part.The most common problems in radiators: Leaks When your radiator leaks it typically is due to leaky hoses, however, it can also be due to leaks in the radiator itself which is a larger issue. The coolant continually running from your radiator to your hot, running engine and back again can create unneeded pressure. That pressure buildup will eventually lead to disaster for your radiator hoses. These hoses can degrade or come loose, which will allow coolant to leave the system—which will result in overheating. The solution here is to replace your radiator hoses regularly as part of standard maintenance.
