Ingredients / Composition
Arsenic alloys are typically created by combining arsenic (As) with metals to enhance properties like hardness, corrosion resistance, and conductivity. Common types include:
Copper-Arsenic Alloy (Arsenical Bronze):
Copper (Cu) – 90–95%
Arsenic (As) – 1–6%
Sometimes with small amounts of tin or lead
Lead-Arsenic Alloys:
Lead (Pb) – 90% +
Arsenic (As) – up to 10%
Used in battery grids, ammunition
Nickel-Arsenic or Iron-Arsenic Alloys (FeAs, NiAs):
Typically used in metallurgy or semiconductor fields
Usage of Arsenic Alloys
Metallurgy: Improves hardness, wear resistance, and corrosion resistance in copper and lead alloys.
Historical Use: Arsenical bronze (copper + arsenic) predates tin bronze and was widely used in ancient tools and weapons.
Electronics/Semiconductors: Gallium arsenide (GaAs) is used in high-speed electronics, LEDs, and solar cells.
Ammunition & Batteries: Lead-arsenic alloys are used in bullet jackets and battery plates for durability.
Glass & Ceramics: Arsenic oxides are used as a decolorizer or clarifying agent in glass production.
