An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot aboard. UAVs are a component of an unmanned aircraft system (UAS); which include a UAV, a ground-based controller, and a system of communications between the two. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator or autonomously by onboard computers.
Compared to manned aircraft, UAVs were originally used for missions too "dull, dirty or dangerous" for humans. While they originated mostly in military applications, their use is rapidly expanding to commercial, scientific, recreational, agricultural, and other applications, such as policing, peacekeeping, and surveillance, product deliveries, aerial photography, agriculture, smuggling,and drone racing. Civilian UAVs now vastly outnumber military UAVs, with estimates of over a million sold by 2015, so they can be seen as an early commercial application of Autonomous Things, to be followed by the autonomous car and home robots.
What can we do?
Corrosion in aluminum alloys
Surface oxide film:
Aluminum is active and readily oxidized. →form thick natural protective oxide layers/films of alumina on surface which protect reactions in the bulk material.
These protective films are stable in aqueous solutions of Ph~4.5-8.5, but not stable in strong acid and alkali solutions.
In aqueous solution, the corrosion product is aluminum hydroxide and then change to →hydrated aluminum oxide, which is less adherent and less protective than ones form in air.
The natural oxide films are of typically 2-3nm thick and mainly composed of Al2O3.
The films will grow thicker with time and depending on conditions.
Coating of oxide films
Film is ~1-2 μm thick.
Al2O3 film is produced by immersion of component in hot acid or alkaline solutions.
The film is composed of mainly Al2O3 with Chromate →increase corrosion resistance.
Used in aircraft structures.
Cr is toxic.
Film is ~10-20μm thick.
Al2O3 film is produced by making the component as the anode in an electrolyte such as 15% H2SO4.
The film is first porous, later sealed.
The film can be dyed to give attractive colours. →architectural products.

We take the CNC machining as core technology, meanwhile, we integrate other upstream and downstream resources in our industrial chain to provide service for the customer.
We have 4 five-axis CNC, more than 30 high-speed CNC machining centers, CNC lathes, CNC carved machines, in total we have more than 50 machining equipment.
Quality control & After-sale service
We will provide all documents as you need such as inspection report, material report, etc. To meet your quality requirements of products and parts.
If the parts have any quality problems when you got them, no matter it happened when we made them or caused by the delivery, we will try best to help you to solve the problems and take our part of responsibility, so you will be free from worries.
