Metal PDF

Microscopic close-up of mild steel sheet metal. Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety metal PDF shapes.


Jelgava, deuxième ville universitaire de Lettonie. En plein c ur des années 90, ce premier roman offre une plongée dans l’univers d’une jeunesse qui s’enflamme pour la culture alternative et le rock metal, et vient donner un éclairage inédit sur le quotidien, après la chute du Mur de Berlin et l’ère soviétique. Un roman générationnel sur la Lettonie, jeune nation européenne encore méconnue en France.

Countless everyday objects are fabricated from sheet metal. Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters.

In the US, the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. There are many different metals that can be made into sheet metal, such as aluminium, brass, copper, steel, tin, nickel and titanium. Grade 304 is the most common of the three grades.

It offers good corrosion resistance while maintaining formability and weldability. Grade 303 is not available in sheet form. Grade 316 possesses more corrosion resistance and strength at elevated temperatures than 304. It is commonly used for pumps, valves, chemical equipment, and marine applications. Grade 410 is a heat treatable stainless steel, but it has a lower corrosion resistance than the other grades. It is commonly used in cutlery. The only available finish is dull.

Grade 430 is popular grade, low cost alternative to series 300’s grades. This is used when high corrosion resistance is not a primary criterion. Common grade for appliance products, often with a brushed finish. Aluminum is also a popular metal used in sheet metal due to its flexibility, wide range of options, cost effectiveness, and other properties. The four most common aluminium grades available as sheet metal are 1100-H14, 3003-H14, 5052-H32, and 6061-T6. Grade 1100-H14 is commercially pure aluminium, highly chemical and weather resistant. It is ductile enough for deep drawing and weldable, but has low strength.
