Inspecting the Quality of Square Metal Tubing

Contractors, architects, and furniture makers are very familiar with square metal tubing, and its versatility as a material. Because it can be cut and shaped to fit various purposes, it is an in-demand product that many trusted metal suppliers always keep in stock. There are varying grades and sizes to choose from, as well as the metal compositions or alloy content.

Naval Brass: Properties and Applications

Historical records show that the use of copper alloys like brass started in Asia at around 5th century BC. Since then, alloys have evolved to become stronger, more durable, and at the same time, more versatile in terms of application. One such alloy that is known for its quality is Naval brass, denoted by international standards as C464.

Getting Good Materials from Copper Sheet Suppliers

Copper sheets are denoted by the international standard name of Alloy C110, also called electrolytic tough pitch (ETP) copper. It is a high-strength material and very resistant to stress. With 99.9% pure copper composition, this metal has been tested and proven to have excellent conductivity.

Supporting Structures

In architecture, copper sheets can be shaped to support structures like skylights, flashing, and roofing elements. This metal has also been used for water fixtures like gutters and spouts because of its resistance to corrosion.

Applications and Uses of Bronze Tubes

Bronze tubes are shaped from Alloy C385, also known in the industry as architectural bronze. Its elemental composition is 57% of copper, with 40% zinc, and about 2.5 to 3% lead. It is the lead content of this alloy that gives it a good thermal conductivity, as well as its resistance to damage when lubricants are applied.

Bronze tubes come in varying lengths and shapes, such as square, round, or rectangular. The tubes are also classified by metal suppliers by their nominal diameters, which is the measure across the outside of the tube. Here are some of the known applications of architectural bronze tubes.

Bronze Bars: Properties and Wide Range of Uses

When it comes to bronze bars, manufacturers often use free-cutting brass or architectural bronze. Most suppliers use the name Alloy C385, and this type of alloy contains 57% copper and 40% zinc, with minimal traces of lead, which is about 3%. For this reason, it is also termed as leaded bronze. It belongs in the major class of bronze used in sculptures and construction.

Used in Home Architecture

Bronze bars of this calibre are also installed in homes for architectural purposes, such as windows, hand rails, and door frames. More often, these bronze bars can be used to manufacture nuts, screw threads, bolts, valve bodies, and pipe fittings.

Resistant to Corrosion

As it is already known, bronze is highly resistant to corrosion from water. Even when exposed to marine atmospheres, such as places near salt water, this metal can withstand the conditions and will never show signs of weakness. Over time, a thin film of copper salt may form on the surface of the bronze, and this is called a patina, giving the metal a unique and aged color.


When bronze is used for certain installations in the home, there are still some limitations to the chemicals that may come in contact with it. For instance, when cleaning bronze details on furniture, one must avoid using ammonia. Using a mild cleaner with a neutral pH, and one specially designed for bronze finishes is better.

If there is a need for a particular thickness and diameter of bronze bars, you can talk to a reputable supplier to find the best deals and the most high quality materials.

Not Just Brass Tubing: Factors that Shape Instrument Tone and Feel

Shipbuilders are selective about naval alloys; sculptors, about architectural bronze or engraving brass. It should be no surprise, then, that many brass musicians have their instruments customized or altered. According to the Acoustical Society of America, brass players believe that what their instruments are made of – and how these materials are used – impact both their sound and feel.

As an instrument-maker, there are a handful of design and construction factors you can work with to craft trumpets, horns, trombones, and other brasswinds that perfectly match their artists. While these factors all start with quality brass tubing, they certainly do not end with that.
