We think this is walnut veneered plywood. This is because it can be cheaper and have the same outer appearance. Plywood does not warp or split over time so maintains its look for a long time. One issue of using this technique is that the glue sticking the veneers on can delaminate.
The housing of the clock face is made from veneered walnut with plywood as the base material. The advantage of this is so the clock is less heavy as plywood is lightweight, but the veneered walnut gives it a more high quality finish. It is also much cheaper and so the overall price of the clock would decrease. Having veneered wood makes it more stable without being prone to warping or splitting.
The plywood has been cut into thin strips and then glued together with PVA and put in a bag press around a mould to give it the curved shape. The walnut is the top layer of the plywood to give it the aesthetically pleasing look.
Wood is one hundred percent sustainable and can be fully recycled to form new products. This prevents unnecessary landfill which is bad for the environment.

This is made from spring steel because it is flexible and so can wind and unwind easily. It also has high hardness and high yield strength.
The spring is the clock is made from
aluminium. It is a very lightweight metal
with a specific weight of 2.7g/com^3.
This is a third of the weight of steel so
would reduce the overall weight of the clock massively. Aluminium is ductile and has a low melting point and density. In a molten condition it can be processed in a number of ways. Its ductility allows products of aluminium to be basically formed close to the end of the product’s design.
The process of making a spring is coiling. It
is generally coiled with a central navigation machine. The wire is pushed forward over a support block toward a grooved head that deflects the wire, forcing it to bend. The head and support block can be moved relative to each other in as many as five directions to control the diameter and pitch of the spring that is being formed.
The recycled aluminium is collected and taken to a treatment plant. Here it is sorted and cleaned for reprocessing. It then goes through a remelt process that turns it into molten aluminium. The aluminium is made into large blocks called ingots where they are sent to mills to be rolled out and then made into products such as cans or chocolate wrappers. www.bing.comhow to make a spring steel - Bing video
There are brass components of the clock is the mechanism to turn the clock hands round. Brass is very easily machined which is one of the best advantages. It is very strong and hard wearing. Durability is one of its key strengths as it lasts a long time. It is also corrosion resistant so if something spilled on it, it would not rust. It is also very easy to clean.
To manufacture brass it involves combining the appropriate raw materials into a molten metal,which is then allowed to solidify. The shape and properties of the solidified metal are then altered through a series of carefully controlled operations to produce the desired brass stock. This can be in the form of rods or sheets.
Brass product suppliers and manufacturers throughout the world depend on recycled brass scrap for their resources. Producing new brass from copper and zinc is simply too uneconomical and also results in a large amount of waste materials. Hence brass is an environmentally friendly alloy and is also hundred percent recyclable.
