What does silicon bronze mean?

Here's a list of possible definitions for the term silicon bronze:

silicon bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as strength, ductility, or machinability. The archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia and India is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age starting from about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times. Because historical artworks were often made of brasses (copper and zinc) and bronzes with different compositions, modern museum and scholarly descriptions of older artworks increasingly use the generalized term "copper alloy" instead.

silicon bronze
Silicon bronze is a type of bronze - a metal alloy primarily composed of copper - to which silicon has been added for additional strength and hardness, as well as improved resistance to corrosion. The amount of silicon can range from around 2% to 6%, making the alloy highly formable, durable, and suitable for various applications. Due to its good strength, high resistance to wear and corrosion, and excellent machinability, it is often used in industries such as marine, electrical, building, and sculpture.
