Ironing polypropylene fabric requires caution due to its low melting point. Always use a pressing cloth to act as a barrier between the iron and the fabric. Set the iron to its lowest heat setting, and avoid direct contact by not pressing down too hard. Instead, lightly glide the iron over the pressing cloth. Test this method on a small, inconspicuous area of the fabric first to ensure there's no damage. If possible, steam can be a safer alternative, as it avoids direct contact, reducing the risk of melting. Always check the fabric's care label for specific instructions, as some polypropylene materials can't withstand heat at all.

The strongest titanium alloy commonly recognized is Titanium 6Al-4V (Grade 5), comprising 90% titanium, 6% aluminum, and 4% vanadium. This alloy is significantly stronger than pure titanium, thanks to its specific blend of materials that enhance its strength-to-weight ratio, toughness, and ability to withstand high temperatures and corrosion.

This makes it highly valued in aerospace, medical implants, and high-performance automotive applications. Its superior mechanical properties and resistance to fatigue and crack growth endorse its status as the strongest and most versatile titanium alloy in the market.

Although titanium is very strong and resistant to corrosion by water and other chemicals. it reacts with common elements like oxygen and nitrogen at high temperatures.
