What is the material of carbon steel plate and what are its advantages and disadvantages

It is a type of steel with a carbon content lower than 2.11% and without intentionally adding metallic elements, and can also be called plain carbon steel or carbon steel. In addition to carbon, it also contains a small amount of elements such as silicon, manganese, sulfur, and phosphorus inside. The higher the carbon content, the better the hardness and strength, but the lower the plasticity.

Introduction to the cutting of aluminium sheets

Introduction to the cutting of aluminium sheets

Sheet aluminium can be cut without the need for a guillotine or tin-snips which tend to deform the metal. With the aid of a straight-edge and a sharp knife "score" both sides of the aluminium sheet. This weakens the aluminium and creates a "fracture line". Place the "fracture-line" over the edge of a table and bend the overhang slightly downwards. Flip the sheet over and repeat. After a few "wiggles" the sheet will fracture along the cut-line leaving a clean break as shown in the above photos. With care and patience full-size sheets of aluminium can be cut using this method. Create a long fracture-line then progressively bend the sheet from one end to to the other. The metal-folder is made from two right-angle sections of metal. My folder is made from aluminium but "angle-iron" is okay. The spacing between the two nuts and bolts determines the maximum width sheet that can be bent. Prepare your work: Mark where you want your bends. Remove any unwanted corners. Fold the aluminium: Now slip the aluminium sheet between the two angle-s and roll the bender forwards while exerting downward body-weight pressure until the fold is 90 degrees. Make a slot along one edge of your folder to accommodate the first bend.Position the first fold such that it will enter the slot when the bend is completed.

The difference between brass and red copper

The difference between brass and red copper

1. Red copper Red copper is pure copper, also known as copper, is copper element, because of its color is purple red and named. Red copper is pure copper refined from sulfide or oxide copper ore, with good electrical and thermal conductivity, excellent plasticity, easy hot pressing and cold pressure processing, a large number of used in the manufacture of wires, cables, brushes, EDM special electro-etched copper and other products requiring good electrical conductivity. 2. Brass Brass is an alloy composed of copper and zinc, brass composed of copper and zinc is called ordinary brass, if it is composed of more than two elements of a variety of alloys is called special brass. Brass has strong wear resistance, brass is often used in the manufacture of valves, water pipes. Air conditioner internal and external unit connection pipes and radiators, etc. 3. The difference between red copper and brass ( 1) Different colors : Brass is pale gold* and red copper is rose-red ( 2 ) Different copper content : Brass contains about 60% copper, zinc has about 40%, and individual brands contain about 1% lead, which is impurities: while red copper contains up to 99.9% copper. (3) Different strength: brass has higher strength, red copper strength is lower. (4) Brass with different density has a higher tolerance than red copper (5) The cutting performance is different, the brass is better, the red copper is poor. (6) the conductivity is different, the brass is lower, the red copper is higher. (7) the corrosion resistance is different, the brass is poor, and the red copper is better.

Properties of stainless steel coil

Properties of stainless steel coil

Stainless steel coil is made from slab, after going to reheating furnace and rolling process, we receive stainless steel hot rolled black coil.Then we have the coil to go through reheating furnace again, then sandblasting and pickling, we get No.1 hot rolled coil in white.After that, we process the coil with rolling and annealing pickling, cold rolled stainless steel coil is produced. Features of Stainless steel coil: 1. Complete product specifications and diverse materials; 2. Excellent surface quality and good brightness; 3. Stable chemical composition, pure steel, low inclusion content; 4. Can be customized. Stainless steel coil is generally very corrosion resistant and will perform satisfactorily in most environments. Pitting is a localised form of corrosion which can occur as a result of exposure to specific environments, most notably those containing chlorides. Crevice corrosion is a localised form of attack which is initiated by the extremely low availability of oxygen in a crevice.
