C10100 copper rod, known as Oxygen-Free Electronic (OFE) copper, is one of the purest forms of copper available, with a minimum copper content of 99.99%. It offers outstanding electrical and thermal conductivity, excellent ductility, and high resistance to corrosion. The absence of oxygen in C10100 minimizes the risk of embrittlement and enhances its suitability for welding and brazing. Widely used in critical electrical applications, it's ideal for high-end audio systems, semiconductor manufacturing, and superconductors. Its high conductivity and purity make it suitable for vacuum environments and sensitive electronic applications, such as telecommunication cables and electronic connectors. Its performance makes it highly valuable in advanced technology sectors.

Stainless steel cold-rolled sheet is a high-precision metal product manufactured by processing hot-rolled steel through a series of reduction rollers at room temperature. This process, known as cold rolling, results in a product with superior dimensional accuracy, a smoother surface finish, and enhanced mechanical properties compared to hot-rolled alternatives.

316L stainless steel pipe is the extra-low carbon version of the standard 316 alloy. The "L" stands for "Low Carbon," specifically limiting carbon content to a maximum of 0.03%. This minor adjustment makes it the industry standard for welded piping systems in highly corrosive environments, as it eliminates the risk of intergranular corrosion caused by welding heat.

C10200 copper, known as Oxygen-Free (OF) Copper, is a high-purity wrought alloy that contains at least 99.95% copper. Unlike standard copper grades, it is produced by melting and casting in a non-oxidizing atmosphere, resulting in a metal that is virtually free of cuprous oxides. This makes it the "gold standard" for high-end electronics and applications requiring extreme conductivity and vacuum integrity.

C12000 copper rod, also known as Phosphorus-Deoxidized, Low Residual Phosphorus (DLP) copper, is a high-purity alloy designed to bridge the gap between standard electrical copper and high-phosphorus plumbing copper. By keeping the phosphorus content very low (0.004%-0.012%), it achieves excellent weldability while maintaining a remarkably high level of conductivity.

Stainless steel hot-rolled plate is produced by rolling steel at temperatures above its recrystallization point (typically over 1000°C). This process allows for the production of much thicker sections than cold rolling, making it the primary choice for heavy-duty structural and industrial applications where thickness and durability are more important than a mirror-smooth finish.

316H stainless steel pipe is the high-carbon variant of the 316 austenitic alloy. While 316L is designed for low-temperature corrosion resistance and welding, the "H" version is specifically engineered for elevated temperature service. By maintaining a higher carbon content (0.04% to 0.10%), it provides significantly better creep strength and structural stability when exposed to temperatures exceeding 500°C.

C11000 copper, commonly known as Electrolytic Tough Pitch (ETP) Copper, is the industry standard for electrical applications. It is the most widely used copper grade globally due to its exceptional electrical conductivity (minimum 100% IACS) and high purity (99.90% Cu).

C10200 copper rod, known as Oxygen-Free (OF) Copper, is a high-purity wrought alloy containing at least 99.95% copper. Because it is produced in a non-oxidizing atmosphere, it lacks the cuprous oxides found in standard copper grades. This makes it the premier choice for high-vacuum technology, cryogenics, and advanced electronics where absolute reliability and maximum conductivity are required.

Brushed stainless steel sheet is a decorative and functional finish achieved by mechanically polishing the metal with fine-grit abrasive belts or brushes. This process creates a unidirectional satin finish, characterized by a pattern of fine, parallel lines that reduce the surface reflectivity without losing the metallic luster.

410 stainless steel pipe is the basic martensitic stainless steel grade. Unlike the 300-series (austenitic) steels you've looked at, 410 contains 11.5% chromium and is heat-treatable. It is selected for applications where a combination of high strength, moderate corrosion resistance, and excellent wear resistance is required at a lower cost.

C28000 brass, commonly known as Muntz Metal or 60/40 Brass, is an alpha-beta (duplex) alloy consisting of approximately 60% Copper and 40% Zinc. It is specifically engineered for its high strength and excellent hot-working properties, making it a staple in marine engineering and heavy industrial fabrication.
