Magnesium is a highly flammable metal, but while it is easy to ignite when powdered or shaved into thin strips, it is difficult to ignite in mass or bulk. Once ignited it is difficult to extinguish. Magnesium, in its purest form, can be compared with aluminum, and is strong and light, so it is used in several high volume part manufacturing applications, including automotive and truck components. Specialty, high-grade car wheels of magnesium alloy are called "mag wheels". In 1957 a Corvette SS, designed for racing, was constructed with magnesium body panels. Volkswagen has used magnesium in its engine components for many years. For a long time, Porsche used magnesium alloy for its engine blocks due to the weight advantage. There is renewed interest in magnesium engine blocks, as featured in the 2006 BMW 325i and 330i models. The BMW engine uses an aluminum alloy insert for the cylinder walls and cooling jackets surrounded by a high temperature magnesium alloy AJ62A. The application of magnesium AE44 alloy in the 2006 Corvette Z06 engine cradle has advanced the technology of designing robust automotive parts in magnesium. Historically, magnesium was one of the main aerospace construction metals and was used for German military aircraft as early as World War I and extensively for German aircraft in World War II. The Germans coined the name 'Elektron' for magnesium alloy which is still used today. Due to perceived hazards with magnesium parts in the event of fire, the application of magnesium in the commercial aerospace industry was generally restricted to engine related components. Currently the use of magnesium alloys in aerospace is increasing, mostly driven by the increasing importance of fuel economy and the need to reduce weight. The development and testing of new magnesium alloys notably Elektron 21 which has successfully undergone extensive aerospace testing for suitability in both engine, internal and airframe components
If you are social you can have a chance of meeting someone through everyday activities such as attending a party, using public transportation, signing up for a gym membership or any other number of things. However, another pain free way to meet someone is by signing up online to dating sites. There are plenty of websites that are free, but some may require a monthly paid membership.

Why are car bodies not made from a low densiy metal like magnesium?
Too expensive
What is the difference between bodies that emit light and bodies that reflect light?
Bodies that emit light produce their own light through a process like thermal radiation or chemical reactions, while bodies that reflect light simply bounce off light that falls on them from another source. Emitting light produces self-generated illumination, while reflecting light allows an object to be visible by reflecting light from external sources.
What does light metal mean?
Light metal refers to metals that have low density, such as aluminum, magnesium, and titanium. These metals are lightweight and have high strength-to-weight ratios, making them valuable in industries like aerospace and automotive for their ability to reduce weight without sacrificing strength.
Can you light a light bulb with pencil lead?
No, pencil lead (graphite) cannot conduct electricity like a metal wire can. In order to light a light bulb, a material that can conduct electricity, such as a metal wire, is needed to create a closed circuit.
At night what are the heavenly bodies you see in the sky?
They are stars that, like our Sun, radiate light. Then there are planets, like Saturn, Mars, Jupiter, etc, that reflects light shinning on them from our Sun.
Which is the result of visible light absorbed by a metal?
When visible light is absorbed by a metal, it can lead to the promotion of electrons from the valence band to the conduction band. This can generate an excited state within the metal, potentially leading to phenomena like photoemission or a change in the metal's optical properties.
Why bodies do not sink in the salty water?
The salt makes the water dense and the object must be heavier like metal or a ship to sink.
Why is a light metal like magnesium not used to make aeroplane?
You think probable to beryllium.
Why are your bodies not made from a low density metal like magnesium?
Well... magnesium is EXTREMLY flammable soo... would you like it if someone lit a match right in front of you NO!
What happens when a ray of light hits metal?
When a ray of light hits metal, some of the light is reflected back, some is absorbed by the metal and converted into heat, and some may cause the metal to emit electrons in a process called the photoelectric effect. This interaction can lead to various phenomena like reflection, absorption, or emission of electrons, depending on the properties of the metal and the characteristics of the light.
What cause the flint in light to explode like a firework?
It doesn't explode it sparks rigid metal(notched metal) causes flint to spark when hit
What things are the color light blue?
The sky on a clear day, some flowers like hydrangeas, certain birds like blue jays, and bodies of water on a sunny day can all appear light blue.
