As is the case with most things, it is almost always to one's advantage to have a number of different choices available. Because it is very difficult and expensive to have too many options without a clear goal for an upcoming CNC machining project, we analyze six factors that should be considered before machining hard or soft metals. These factors include the type of metal to be machined, the type of tooling to be used, and the material to be machined.

 

Mechanical Properties of Metals: To begin, let's talk about the material's mechanical properties, which can be defined as how it responds when subjected to a variety of different forces. The following are some of the most important mechanical properties to take into account when working with metals: strength, ductility, elasticity, hardness, density, magnetism, fracture toughness, the range of fracture toughness is highest of all metals, but the range from soft to hard is the hardest, damping (hard metals tend to have a small damping capacity), and fracture toughness. If any of the aforementioned properties are essential to the completion of your project, we strongly advise that you conduct some research to obtain actual property ratings for each type of material. You can find an exhaustive list of all of our metals, in addition to links to detailed data sheets, on the materials page of our website.

1. the resistance of metals to fatigue and abrasion
There are a lot of different resources available for environmental cycling testing. In most cases, the materials are put into a controlled environment and tested for high temperatures and low temperatures, high humidity and low humidity, thermal cycling and thermal shock, and so on.When machining a part for prototype fit and function, you typically do tool steel not need to be concerned about material wear. However, there are some exceptions to this rule.If you need to test the strength of the parts or the parts' ability to withstand environmental performance such as extreme temperatures, selecting the appropriate material is very important.Let's take a look at the factors that contribute the most to fatigue.

 

The amount of stress that a material is able to withstand for a predetermined amount of repetitions is referred to as its fatigue strength and toughness. These variations have been thoroughly researched to assist in making the appropriate material selection to fulfill the requirements of your end use. According to studies conducted on the topic, it is believed that fatigue is responsible for approximately 90 percent of all failures that occur in metals. As a result of failure occurring suddenly and without any prior warning, fatigue strength is typically measured by averaging ratios. It is recommended that when choosing a material, if you are aware that the component will be put through multiple stress cycles, you evaluate the fatigue strength rating of the material.

 

metal surface finishing

 

There is a wealth of information available for conducting environmental loop testing. The vast majority of materials undergo testing in conditions that feature low humidity, low temperature, and high temperature, respectively. Titanium and stainless steel are examples of metals that can withstand high temperatures; copper and aluminum are examples of metals that can withstand extremely cold temperatures while maintaining their ductility at low temperatures. The capability of a material to resist creep is what is meant by the term "creep resistance. "The tendency of a solid material to change shape over an extended period of time as a result of being subjected to high levels of stress is referred to as creep. Because it lasts for longer periods of time, creep resistance has a better chance of surpassing the material's standard stress limit. This is an important fact to keep in mind. In use cases that may be subjected to high temperature environments, such as aerospace applications or spacecraft, creep is of utmost importance. The composition of an alloy and the temperature at which it melts both have an effect on the creep resistance of a metal. The metals with the highest creep resistance are nickel, titanium, and stainless steel. Nickel, titanium, and stainless steel. Because of its typically low melting temperature, aluminum is not an ideal material for use in aerospace applications.

 

2. the ability of metals to resist corrosion
Corrosion of metals is caused by chemical reactions that take place between the metals and their environments, and can take the form of either degradation or oxidation.Corrosion can occur in metals for a variety of different reasons, and it is important to keep in mind that all metals eventually corrode.Iron in its purest form tends to corrode very quickly, whereas stainless steel, which is made by combining iron with other alloys, tends to corrode very slowly.If you are concerned about corrosion, stainless steel is a material that you should consider using.

 

Anodized aluminum is yet another material that CNC milling china can serve as an alternative to stainless steel. This finish is extremely long-lasting and helps prevent corrosion at the same time. Because anodizing is a secondary service, it may lengthen the amount of time it takes to complete the project; consequently, it may not be practical for the requirements of your project.

 

3. the thermophysical characteristics of metals
Although we have had some experience with it, the reaction of metals to heat and pressure can be quite varied.The following table provides a breakdown of various metals and their electrical and thermal properties. Some of the changes that can occur with metals include expansion, melting, and conductivity of electricity..

 

4. The ability of metals to be manufactured
When it comes to the ability to be manufactured, each potential supplier or manufacturing partner may have a unique set of requirements based on the capacities that they possess.If you find that your part cannot be machined and you have little flexibility in the design of your part, you may need to change your manufacturing method to 3D printing, which can offer unique solutions in both metal and plastic. If you find that your part cannot be machined and you have little flexibility in the design of your part, you may need to change your manufacturing method to 3D printing.If you decide to machine your part and upload a quote, the good news is that we will provide feedback on the design for manufacturability of your part with each quote..

 

5. Metal cost
Before deciding on a material, the final significant consideration we will look into is the price.If you have more financial requirements or needs, then it is highly likely that you will pay a higher price for these materials. This information may or may not come as a surprise to you.If you weigh the cost of machining aluminum against some of the other features that we discussed earlier, you will find that aluminum is a relatively inexpensive material.If you are unable to make any trade-offs, we suggest consulting your DFM to optimize the design of your part, which will save you both time and money regardless of the material you choose.
