The film thickness of hard anodized aluminum machined parts:

1. film thickness of hard anodizing, usually between 25μm-150μm, with most hard anodizing films having a thickness of 50μm-80μm;

2. Hard anodized films with a film thickness of less than 25um are commonly used for parts in applications such as tooth keys and screws; the thickness of anodized films for wear resistance or insulation is about 50um; only in special environments, such as high temperature, high humidity, high pressure, etc., will hard anodized films of 125μm or more be required; (products used in marine environments and in environments with high-temperature plasma radiation from medical device equipment, the requirements (very demanding, from product validation to mass production).

3. It should be noted that given the property of hard anodized films to be produced in both directions, the actual unilateral increase in film thickness is 50μm for hard anodizing with 100μm film thickness; It should also be noted that the thicker the hard anodized film, the lower the microhardness of the outer layer (the more brittle the oxide film) and the more the surface roughness of the film will increase.

Packing: Inner is Poly foam, out is carton. Then pallet. Carton size: 29*19*19.5CM and 23.5*17.5*8, CM and pallet size is: 215*100*90CM, or as your requirement.

Packing for CNC Aluminum parts:

1. Usual packing: By pearl cotton/bubble bag/plastic wrap + carton box, 0.5-10kg/carton box.

2. Special packing(for large part/large quantity order): By pearl cotton/bubble bag/plastic wrap +carton box+wooden box.

3. As customers' requirement for CNC aluminum parts
