What Is Silicon Bronze?
Silicone bronze alloy is an alloy of aluminum and tin which has excellent corrosion resistance properties. It is comparatively lighter in weight and is also less dense. Its chemical formula is SiO2. The alloy's chemical properties are similar to the porbo cavalleria porosity, meaning that it is moderately elastic and ductile, but not ductile enough for use in high-precision CNC machines. There are some differences from the conventional magnesium and iron alloys that might be useful for applications in aerospace.
For the most part this alloy is used for the fastener component of any CNC machine. The material features high tensile stress area and it is capable of resisting both axial and radial load. This means that it can be used for fastener replacement in CNC machinery, such as bolts in the case of bolt head removal or threads in the case of threads in the mating of threaded rods. The material is also frequently used for reinforcement in high-stress areas in CNC machinery, such as fatigue wear, stressed metal fatigue or straightening stresses in CNC lathe heads.
The most important and beneficial property of the silicon bronze alloy is its corrosion resistance. As it is ductile, it can resist many types of corrosion. Commonly occurring corrosion of this material is friction due to temperature changes and/or air exposure. In these cases, it is usually advisable to lubricate the bearing to prevent the formation of cracks. Anytime the bearing has been subjected to extreme temperatures, it should be inspected for signs of galvanic corrosion resistance. High-quality bearing bolts made from this alloy will typically feature a special black coating which further protects against corrosion.
Silicon bronze alloys feature excellent tensile strength. They have been tested and found to be as hard as cast iron and as soft as cobalt. They have excellent thermal conductivity and therefore are often used as bearing fasteners for machinery. Because of their unique combination of hardness and corrosion resistance, they are often used in conjunction with magnesium for the construction of mechanical components. They are also used as bearings in CNC machinery and are often incorporated into the casting of precision parts. In fact, the alloys are so popular that there is a thriving aftermarket for them.
Like alloys, the properties of the silicon bronze alloy are subject to damage under certain conditions. The most common issue with them occurs when they have been exposed to an elevated temperature. When the temperature goes up, the surface of the alloy begins to develop a yellowish or rusty color. This is a common occurrence and does not affect the overall quality of the part. In some cases, this process of rusting may occur even if the part is not heated.
One of the most common places where the silicon bronze alloys are used is in aircraft structures. They are commonly used as bearing stiffeners, and in airplane landing gears and other moving parts. They are also frequently incorporated into the design of fuel tanks and airframes because of their excellent corrosion and erosion resistance properties. This means that they can be used as coating material for many different types of metal surfaces, protecting them from corrosion and further damage.
