![]() ![]() Interestingly, bronze reacts with a wide range of substances and chemicals, and the oxidation process can even bring out unexpected colors and patterns. The various methods and substances involved can have different effects, too. There are even specialized products for this purpose like Cool Tools Patina Gel ($14). Unfortunately, most of them are somewhat smelly, involving anything from eggs or vinegar to ammonia or other substances that speed the oxidation (patina) process. Over months of wear it'll naturally take on a worn, distressed look that's unique to the wearer, his or her lifestyle and climate.īut what if you're impatient? What if you want to post it on Instagram now? There are a number of methods for achieving instant patina gratification. The use of bronze as a watchmaking material was once considered trendy but is now firmly established, part of the bronze's appeal being its tendency to form a patina over time. Other Metal Resources by Sequoia Brass & CopperĪt Sequoia Brass & Copper, our team works hard to meet all of your copper, brass, and bronze needs.You say you want your watch to look like it was dredged from a sunken relic? It's "cool," you say? Well, you're not alone. With over 30 years of experience sourcing and buying alloys, we have the knowledge and skills to source specialty and hard-to-find copper alloys for your unique needs. Sequoia Brass & Copper has been sourcing and cutting metal since 1983 and currently maintains ISO 9001:2015 certification. We provide custom cutting services that adhere to tight tolerances of ☐.020 inches to facilitate the customization of these materials to suit different applications and specifications. Metal & Alloy Offerings by Sequoia Brass & CopperĪt Sequoia Brass & Copper, we offer metals in a variety of forms, including: Its durability and hardness also enable it to withstand the stress of marine applications. Bronze is best suited for resisting corrosion in saltwater and sea environments. Tools and equipment intended for marine environments need to have a high degree of resistance to corrosion.It can be used for decorative components, metal pieces that people come into contact with regularly (such as doorknobs), and food-grade surfaces that need to be anti-bacterial or anti-microbial. It’s malleable, easy to cast, relatively inexpensive, and low-friction. Brass is often considered the most suitable for general applications. Copper is highly flexible with excellent conductivity, while bronze and brass offer greater machinability. Pure oxygen free copper offers the greatest flexibility, ductility & conductivity. While each of the three metals is durable, they do not exhibit the same level of flexibility.Some of the key differences to keep in mind when selecting sheet metal materials include: Although copper, brass, and bronze provide electrical and thermal conductivity, corrosion resistance, and strength, there are distinct differences between the three metals. Additionally, it demonstrates suitability for hot forming and hot forming, as well as drawing, bending, heading, soldering, brazing, and welding.Ĭhoosing the right type of metal for an application is critical to designing and manufacturing a high-quality part or product. Alloy 464. Alloy 464 (or naval brass) is known for its excellent resistance to corrosion from seawater across a wide range of temperatures.Alloy C48200 – C48500. Leaded naval brass meanto for machining.Alloy 385 is available in a wide variety of extruded & drawn shapes such as angles, channels, square tube, hand rail moulding & more. Alloy 385. Also known as architectural bronze this alloy can be used for construction & architectural applications.It commonly finds application in the manufacture of hardware components, fittings, valves, and fasteners. It exhibits excellent machinability and formability, as well as suitability for soldering and brazing operations. Alloy 360. Also known as free cutting brass, this alloy is the most common type of brass.Alloy 353. Alloy 353 (also referred to as clock brass) is often used to fabricate precision components, such as clock and watch parts, because of its excellent machinability.It contains a low lead content sufficient for cold-working and is commonly used to produce pipes. Alloy 330. Brass alloy 330 is suitable for application where high machinability is critical.It is typically used in industrial and architectural applications. Alloy 272. This alloy-also referred to as yellow brass-consists of 33% zinc.It is suitable for use in ammunitions, automobiles, fasteners, and hardware. Alloy 260. Also known as cartridge brass, Alloy 260 demonstrates good cold working properties.At Sequoia Brass & Copper, we provide these six grades of brass: Brass is available in a variety of grades, each of which is characterized by the exact material makeup.
