Dawopu Design and Manufacturing delivers innovative solutions to manufacturers through product design, engineering, and manufacturing of precision components and assemblies. Our experience covers a wide range of applications that require tight-tolerance fabrication. Primary industries served include medical, appliance, HVAC, engineering,Machinery,and office furniture manufacturers.

But our real value is in bringing our design and manufacturing experience to bear to improve profit margins and delivery times for our clients. Two ways in which we accomplish these objectives are through cnc ,rapid prototyping and 3D laser welding.

Anti-magnetic steel

Non-magnetizable steels

These stainless austenitic steels are characterized by high strength and corrosion resistance, even against salt water, and cannot be magnetized due to the alloy with manganese or molybdenum. Non-magnetizable steel is also known as submarine steel.

Typical material numbers are

High temperature resistant

Heat-resistant steels

Heat-resistant ferritic steel can withstand high thermal loads and, thanks to its alloying with chromium, silicon and aluminum, retains its good strength properties even when exposed to hot gases and combustion products.

Typical material numbers are

Noble be the steel

Rust and acid-resistant steels

Chromium-nickel steels with high corrosion resistance and strength are referred to as rust and acid-resistant. They are also referred to as stainless steel, other designations are V2A or V4A. The chromium content of the stainless steel (min. 12 %) forms a wafer-thin layer of chromium oxide in combination with oxygen from air, water or other media. This protects the steel underneath. If the layer is damaged, it forms again.

Typical material numbers are

Heat resistant

High temperature steels

High-temperature steel is specially alloyed and is characterized by the fact that it largely retains its material properties (strength, elasticity) even at high temperatures.

Typical material numbers are

Permanent

Engineering steels

Engineering steel is used where higher strength is required (e.g. chrome-molybdenum steel) and/or to replace steel grades that are to be protected against rust by galvanic protection, galvanizing or painting. (VA steel)

Typical material numbers are

Everything but iron

Non-ferrous metals

Non-ferrous metals are all metals that do not contain iron as the main element. Common examples are copper alloys such as Kuprodur, aluminum alloys or magnesium alloys. Non-ferrous metals are also included.

Typical material numbers are

Conductive and sliding

Kuprodur®

Kuprodur® (= brand name of Herm. Sprenger Metallwarenfabrik, there is also the Carodur® brand from Buntmetall Amstetten, both are also known as cupronickel silicon) is an alloy of copper, nickel and silicon that combines high strength and hardness with very good corrosion resistance. Kuprodur also has high electrical conductivity, conducts heat well, is durable and shows little wear.

Kuprodur screws and fasteners made of Kuprodur® are therefore used in mechanical and electrical engineering for connections and electrical contacts that are exposed to the elements or subject to high mechanical stress. In vehicle construction, Kuprodur is used for valve guide bushes and is also suitable as a bearing bush for plain bearings subject to high thermal loads.

Special materials

Special materials

Special materials are characterized by their suitability for very specific tasks. When it comes to extreme operating temperatures, maximum strength or when the operating conditions are particularly stressful or corrosive, special materials are required. Some special materials also have impressive qualities when it comes to lightweight construction.

The extremely high resistance to certain challenges is typical of many special materials. The processing of these superalloys is correspondingly demanding and requires comprehensive expertise and adapted CNC technology.

Permanent EdeL

Ferralium® Alloy 255

Ferralium® Alloy 255, a Langley Alloys brand, is a stainless steel with particularly high strength and very good corrosion resistance.

Active in the resistance

Hastelloy®

Hastelloy® is a brand name of Haynes International for high-resistance alloys with a high nickel content. Depending on the alloy, the material is optimized for heat resistance or corrosion resistance.

At home in chemistry

Incoloy®

Incoloy® is a brand of the Inco Company and stands for highly resistant nickel-iron-chromium alloys, which are used in particular in chemical and petrochemical process engineering.

For the extremes

Inconel®

Inconel® is a trademark of Special Metals Corporation for corrosion-resistant nickel-based alloys suitable for high-temperature applications in extreme environments.

Extremely acid-resistant

Monel®

Monel® is a brand name of Special Metals Corporation for nickel-copper alloys with high strength and extreme corrosion resistance, for example to media such as seawater, hydrofluoric acid or sulphuric acid.

Thermally stable

Nickel alloys

Nickel alloys have very good corrosion resistance and are resistant to high temperatures. They exhibit low thermal expansion.

Nickel inside

Nimonic®

Nimonic® is a brand name of Special Metals Corporation for tensile nickel-chromium alloys with high corrosion and oxidation resistance.

Chemical specialist

Tantalum

Tantalum is a heavy metal that is twice as dense as steel. Tantalum conducts heat and electricity very well and is resistant to heat. Its melting point is just over 3,000° C. Together with its high hardness and corrosion resistance, these properties make tantalum the ideal material for components in the chemical industry. Tantalum components are also used in electronics and automotive engineering.

Customized production

Titanium

Titanium has a low density and high tensile strength. The material is around 40 % lighter than steel, but achieves similar tensile strengths. Titanium is also highly corrosion-resistant and anti-magnetic.
