A sheet metal brake is a tool used to bend sheet metal. There are different types of brakes, from small tabletop models to large hydraulic ones. They can be used for various applications, such as bending ducts or guttering. A sheet metal brake is a tool used to create folds or creases in a piece […]
Metal spinning is a cost-effective method used to shape ductile metals into symmetrical shapes using a lathe and a shaping tool. It is often used for small batches and decorative pieces, and can be controlled by hand or CNC. The process increases the tensile strength of the metal and allows for easy design changes. Metal […]
Cold metal cutting saws are lightweight, hand-held saws used to cut thin sheet steel without heating the blade or material. They preserve the sharpness of the blade and anti-corrosion coating on the cut edge. They are primarily used by sheet metal repairers for efficient cutting and trimming of thin sheet metal and corrugated iron often […]
Metal detectors use Lenz’s law to generate an oscillating field that detects conductive objects. Pulse induction technology can detect objects under mineralized sand. Applications include locating mines and searching for buried treasure. According to Lenz’s law of electromagnetism, when a conductor falls within a certain range of an oscillating (alternating) magnetic field, it generates its […]
Brushed metal is created by sanding or abrading metal to create a less reflective, decorative finish. Different textures are achieved using different grits of sandpaper or abrasive cloths. Common metals used include nickel, aluminum, and stainless steel. Brushed finishes are often considered more elegant and are commonly used in building fixtures, appliances, and decorative items. […]
Metal cladding is a protective and aesthetic exterior or interior covering for buildings. Metal siding is versatile and durable, with different types of metals and coatings available. Aluminum is popular for its resistance to rust and corrosion, while steel is strong but prone to rust. Copper is chosen for its aesthetic appeal and is often […]
Metal chelation therapy removes toxic metals from the body using chelating agents. It is approved for heavy metal toxicity only and has no effect on other conditions. Different compounds are used for different metals. Chelation therapy can cause serious side effects and requires long-term treatment under medical supervision. Metal chelation is the process of using […]
Electrical Metal Conduit (EMT) is a lightweight, cost-effective option for enclosing electrical wires. It is made of steel or aluminum and often galvanized to resist corrosion. EMT is popular for indoor and outdoor use, easy installation, and controlling the flow of electricity. However, it may not be suitable for all applications, such as when a […]
Precious metal refining involves purifying metals through pyrometallurgy or hydrometallurgy. Preparation includes sampling and creating an assay. Pyrometallurgy involves heating and melting to separate impurities, while hydrometallurgy dissolves metals in a solvent. Zone refining is a highly effective but expensive purification process. Hydrometallurgy involves leaching, purification, and recovery of precious metals through various methods. Precious […]
Sheet metal is a versatile material used for various tasks, available in different gauges and grades. It can be treated with coatings and comes in flat sheets or rolls. It is sold at hardware stores or directly through fabricators, and high volume contracts result in lower costs. Sheet metal is metal formed into flat sheets […]
Filler metal is used to join two pieces of metal together during welding or soldering. Different types of filler materials are available, such as covered electrodes, bare electrodes, and flux. The choice of filler metal depends on factors such as material strength match, shape of metal objects, and fire or corrosion resistance. Filler metal refers […]
Metal spraying is a process of coating surfaces with metal or alloys using spray equipment. It is used to protect metals from corrosion and to harden softer metals. The process involves melting the metal and spraying it onto the surface. The equipment is portable, making it easy to use on complex surfaces. Metal spraying is […]
Metallic adhesives, such as polyurethane, epoxy, resin, and Liquid Nails®, are preferred for joining metal. Each type has unique properties, such as strength, flexibility, water resistance, and fast drying. Proper surface preparation is necessary for best results. Any number of projects might require joining two or more pieces of metal together. In most cases, the […]
Metallic adhesives like polyurethane, epoxy, resin, and Liquid Nails® are recommended for joining metal pieces. Polyurethane is strong, flexible, and water-resistant, while epoxy fills gaps and resists impact and chemicals. Resin is slow to dry, but acrylic dries quickly and withstands extreme weather. Liquid Nails® is inflexible and waterproof. Proper preparation of the metal and […]
Welding is the process of bonding materials by melting metal or thermoplastic surfaces. Arc welding is a common metal welding process that uses a high energy power supply to create an electric arc between the welding tool and the material being welded. Gas metal arc welding (GMAW) and flux core arc welding (FCAW) are two […]
Metal lathes are used to machine, carve, and cut metals like steel, brass, and iron. They consist of various components, including the headstock, bed, feed and screws, carriage, cross slide, compound holder, tool holder, and tailstock. The metal is rotated at a fixed rate while cutting bits made of carbide or other hardened material are […]
Metallurgical jobs in mining and materials engineering include project management, consulting, technical manager, and research. Education and experience are required, with opportunities available worldwide. The mining industry is growing, and metallurgists can specialize in traditional mining or materials engineering. Research focuses on extraction techniques, waste management, environmental impact, economic viability, and social responsibility. In the […]
Etching is a technique of cutting a surface using acid, used by artists such as Dürer and Goya. Metal engraving is an industrial and artistic technique, and can be done using chemical, photochemical or electrochemical processes. It is used in various industries and by artists such as Cedric Green. Etching, from the German word meaning […]
