FAQs and Answers

Here are some answers to the most common questions about Aluminium and its advantages … for users and consumers

Is Aluminium economical, safe and ecologically sensible?
  • Aluminium is the most commonly used metal after steel
  • Aluminium is the most abundant metal in the earth’s crust
  • Aluminum is the third most abundant chemical element on earth after oxygen and silicon
Are Wyda Containers Microwavable?

Yes they are! Just follow the steps shown in the video if you want to use Wyda aluminium containers safely in a microwave.

Rim Styles

IVC (Interrupted Vertical Curl) designed for closing board and / or PET lids onto rectangular foil containers. The sides will be curled, but corners left with raw foil edges.

Full Curls conceal the raw foil flanges and add rigidity to the container in a pleasant look. Clip on PET lids are available to some products.

Hygienic

The smooth surface is easy to clean and odorless. Aluminium is therefore ideal for use under sterile and germ-free conditions – areas with high hygienic requirements such as laboratories, hospitals or food processing.

Fully recyclable

The extraction of aluminum is energy intensive, but old aluminum can be easily melted and reused 100%. Only 5% of the energy is consumed!

Lightweight and very stable

The density of aluminum is about 2.6 to 2.8 g per cm 3. This is about 1/3 of the density of steel, which is why aluminum is also called “light metal". Despite its low weight aluminum has a very high strength.

Vapor-impermeable

Even with an extremely long shelf life, moisture cannot diffuse through the metal.

Impact-resistant and high strength

The surface of an aluminium plate is dented by impact, but the impact energy is absorbed by the deformation. This property is important for almost all WYDA products. It makes them durable and extremely durable even under unfavorable conditions.

Insensitive to temperature fluctuations

The material properties remain constant in the temperature range from -80 to +150 ° C. Even extreme temperatures tolerate aluminum without losing its properties. In extreme cold, aluminum becomes even harder and its hardness increases!

Resistant to UV radiation

Long durability and extreme UV radiation have no effect on this material.

Corrosion-resistant and protects itself

When exposed to oxygen from the air, the aluminium surface is coated with a dense oxide layer, which, if damaged, is immediately renewed and the underlying metal is protected against corrosion.

Magnetically neutral

Aluminium is free from ferromagnetism. For certain applications, e.g. in laboratories, this material property can be of great importance.
