Metallurgy is the branch of science and technology that deals with the properties, production, and applications of metals and alloys. Metals are naturally occurring chemical elements that possess unique physical and chemical properties that make them useful for a wide range of applications. From jewelry to construction materials to electronic components, metals are an essential part of our everyday lives.
In this blog post, we will explore the different types of metals and alloys used in metallurgy, and what people with sweaty body or hands or someone with allergies should take note of.
-
Stainless Steel: Steel is an alloy of iron and carbon, with other elements such as manganese, silicon, and sulfur added to modify its properties. It is used in a wide range of applications, including construction, transportation, and manufacturing. People with sweaty hands should avoid prolonged contact with steel as it can cause rust and corrosion. The percentage composition of these elements can vary depending on the specific type of steel. For example, a typical carbon steel might contain approximately 0.5-1.5% carbon, 0.6-1.8% manganese, and 0.2-0.5% silicon.
-
Aluminium: Aluminium is a lightweight, silvery-white metal that is used in a variety of applications, including packaging, construction, and transportation. It is corrosion-resistant and does not rust, but can cause skin irritation in people with allergies. The percentage composition of aluminium is approximately 99% aluminium and 1% other elements such as copper, magnesium, and zinc.
-
Copper: Copper is a soft, reddish-brown metal that is used in electrical wiring, plumbing, and industrial applications. It is a good conductor of electricity and heat, but can cause skin irritation in people with allergies. The percentage composition of copper is approximately 99% copper and 1% other elements such as zinc, tin, and nickel.
-
Brass: Brass is an alloy of copper and zinc, with other elements such as lead and tin added to modify its properties. It is commonly used in plumbing fixtures, musical instruments, and decorative items. Brass can cause skin irritation in people with allergies. The percentage composition of brass can vary depending on the specific type of brass. For example, a typical brass might contain approximately 60-70% copper, 30-40% zinc, and small amounts of other elements such as lead or tin.
-
Bronze: Bronze is an alloy of copper and other metals, such as tin, zinc, and nickel. It is used in sculpture, jewelry, and decorative items. Bronze can cause skin irritation in people with allergies. The percentage composition of bronze can vary depending on the specific type of bronze. For example, a typical bronze might contain approximately 88% copper, 10% tin, and 2% other elements such as zinc or nickel.
-
Titanium: Titanium is a lightweight, strong, and corrosion-resistant metal that is used in aerospace, medical, and industrial applications. It is hypoallergenic and does not cause skin irritation. The percentage composition of titanium is approximately 90% titanium, 6% aluminium, and 4% vanadium. At Deema & Co., any of our titanium jewellery is made of a high grade.
-
Nickel: Nickel is a silvery-white metal that is used in stainless steel, coins, and batteries. It can cause skin irritation and allergic reactions in some people, especially those with sensitive skin. For example, a typical austenitic stainless steel might contain approximately 8-10% nickel.
-
Gold: Gold is a precious metal that is used in jewelry, coins, and decorative items. It is hypoallergenic and does not cause skin irritation. The percentage composition of gold in jewelry is typically measured in karats, with 24 karat gold being pure gold (100% gold) and lower karatages indicating varying amounts of other metals such as copper, silver, or zinc. For example, 18 karat gold might contain approximately 75% gold and 25% other metals.
-
Sterling Silver: Silver is a white, lustrous metal that is used in jewelry, coins, and decorative items. It is hypoallergenic and does not cause skin irritation. The percentage composition of silver in jewelry is typically measured in terms of its purity, with pure silver being 99.9% silver and other grades such as sterling silver containing 92.5% silver and 7.5% other metals, typically copper.
People with sweaty hands or body should be aware of the metals they are wearing as sweat can cause corrosion and discolouration over time. It is recommended to remove jewelry and other metal items before engaging in activities that may cause excessive sweating.
In conclusion, metallurgy is an essential field that plays a vital role in our everyday lives. Understanding the different types of metals and alloys, and their properties, can help us make informed decisions when choosing materials for different applications. People with allergies or sensitive skin should be aware of the metals they are wearing and take necessary precautions to avoid skin irritation or allergic reactions.
