Cold rolling increases the yield strength and hardness of a metal by introducing defects into the metals crystal structure. Cold Rolling is most often used to decrease the thickness of plate and sheet metal in the manufacturing stage. Since cold-formed steel is formed at room temperature, the material becomes harder and stronger. The cold roll process results in improved gauge tolerances, as well as a smooth, attractive appearance. Cold rolled steel is generally free of rust or scale and is easy to work, paint or chrome. Not only are the tolerances (thicknesses) looser on hot rolled steel, but often the "squareness" (edges and finish) of the product are not as precise as well.
Metals can be classified as either ferrous or non-ferrous. The basic difference is simple: A ferrous metal is iron or an alloy that contains iron, while non-ferrous metals consist of any metal other than iron, along with alloys that do not contain an appreciable amount of iron.
Common ferrous metals include carbon steel (1018, 12L14), alloy steel (4130), stainless steel (304, 316), and wrought iron. Common non-ferrous metals include aluminum and its alloys (3003, 5052, 6061, 6063), precious metals (gold, silver and platinum), copper and its alloys (brass and bronze), titanium, and nickel.
乍一看，两种类型的金属之间的差异可能并不明显。但是，根据金属的预期使用，差异可能很重要。亚铁金属通常成本较低，而且耐用性，尽管大多数因铁含量而易受生锈和腐蚀。实际上，识别亚铁金属的一种方法是寻找生锈 - 通常，如果您看到生锈，那是铁色的（除了锻铁，除了铁铁矿，一种抵抗生锈的铁质金属）。
Ferrous metals make up the backbone of our infrastructure, including buildings, bridges, railroad tracks, trains, heavy equipment, and automobiles. They also make up the bulk of manufacturing equipment and tools, as well as household appliances.
Non-ferrous metals are non-magnetic and have high conductivity, which makes them useful for certain electronics applications, such as wiring. Even though they aren’t attracted to magnets, non-ferrous metals also can be recycled easily. Aluminum is the third most recycled metal, globally.
Industrial Metal Supply is a full service supplier of all types of metals, both ferrous and non-ferrous, and metal accessories, metalworking equipment, and supplies. Visit one of our六个位置in Southern California and Arizona today.
Are steel and aluminum, or (Ferrous and Non-Ferrous) gauges the same thickness?
Stainless steel: Gauge
Aluminum: Decimal (i.e. .032 or .060)
Why is copper thickness called out by the ounce (i.e. 24oz.) and not the actual thickness?
Just because. Quite frankly, we don’t have a better answer for this one! The ounce represents the weight per square foot that the material weighs. For example, 32oz (.042) thick is twice as thick as 16oz. (.021) thick.
Can IMS guarantee that the item I order will telescope into one another?
Unfortunately, it would be hard for us to guarantee that the items you order will all telescope. If this is important to you, we do carry two lines of products that are guaranteed to telescope. One is our 6063 T8 Brite finish, aluminum grade tube – starting at ⅜” OD (outer dimension) and ranging up to 1 ¾” is manufactured to telescope so this product will fit together. All wall thicknesses are .058 thickness and are stocked in ⅛” OD increments. We also stock a product called telescoping tube that is made to slip-fit. You can find thissteel tubing在我们网站的“产品”部分中。
We are proud to have employees who know a lot about metal, but we are not in a position legally or professionally to offer technical advice. We are happy to answer any questions we can but any technical advice given is without charge, and we will have no obligation or liability for the advice or the results. Any recommendation we offer is being given and accepted at buyer's risk.
What is the difference between alloys?
Please refer to theGlossarysection of this website. We have listed many of the common alloys and their definitions to help you out with this answer.
Which is stronger?
Steel is stronger than aluminum pound for pound, but there are different alloys, tensile strengths, etc. that play a role in determining this answer. Within the steel category, cold rolled is a little stronger and harder than hot rolled.
Which bends better – hot rolled or cold rolled?
Hot rolled bar or sheet will bend slightly easier with a tighter radius than cold rolled steel will bend.
Do you do any fabrication in-house?
What other capabilities do you have in-house?
We have five branches with high end equipment in each warehouse. We do metal processing for our customers everyday and can do anything from Ironworker through 6-Axis 3D laser cutting.
Can you mitre cut?
Yes, but only tubes and shapes using our new state-of-the-art Mazak laser cutting machine. For more information on its capabilities check out theLaser cutting capabilities。
Can you cut woven and welded sheet to size?
Unfortunately we cannot cut woven wire sheet to size at this time. Sheets must be taken in their full size。
