sometimesCopper waste will appear at our home。For example, the copper wire is not used.,For example, the generator on the tractor is not,These copper waste will be sold by us。
But when sold,People who collect waste,Black bronze,Anyway, the price of brass is expensive.,Brass is cheap。
(antique brass tube fittings) One bronze classification,He is not annoying,We are in trouble。Give money,Don't be classified here.,Get headache。(antique brass tube fittings) Why is copper divided into brass and brass??What is the difference between these two copper??Only these two categories have copper??If there are only two categories,So what is the bronze of ancient unearthed??

But,People are most afraid of being curious。For example, I personally curiosity,Much more interest,And most of the rare weird interest。Sometimes it's okay.,I will think of any red bronze is more than yellow.?Not all copper??But it is expensive,I must have expensive truth,What is the truth in this??
Let's talk about the difference between brass and brass today.,Let's talk about what ancient bronze is。

Ⅰ:What is the difference between brass and brass??
How red bronze is more than yellow?Is it noble because it's color??
Of course not this,The metal itself will not be rich or poor,Their value is given by people,And the fundamentality of their value depends on their process complexity and their role.。So,What is the difference between brass and brass??
First come, bronze,From the angle of metal,Only red copper is true copper,Means of,Bronze is pure copper。
(antique brass tube fittings) Red copper melting point is1083Spend,When the copper ore attached to the copper element is mined up,Will be refined in vulcanized cave。The refining process of copper is almost almost,But what we said is almost the step procedure,The raw materials and methods used in both are completely different.。

Brass profileBrass Profiles
For example, the cast iron needs to enter after secondary constraints into iron water.“Converter”Medium blowing oxygen removal part impurities。The high-quality copper mine is smelted after the fire is fired.,Produce melting(Ice bronze)It is also necessary to be sent into the converter for blowing.。
Both are actually similar here.。but,The furnace of the refined copper mine is divided into many,Reverse furnace、Electric furnace, etc.。The crude copper from the converter will be sent to another furnace to remove impurities and refinement,Get purity of almost 100 pure copper。
This is the most traditional abundry method,It is called fire-making copper,It is the most widely used refining process.。
One of its first requirements is to take the temperature to melt,In the past handmade era,And the past,It is not easy to think about such copper.。
but,The value of copper is never distinguished by melting point.。
So,Is the brass melting point??Not low!Its melting point1193Spend,It's more pure copper than red copper.。so,Not to determine their value with high melting point。
(antique brass tube fittings) Brass is actually doped with alloy copper of other metals.,It will be doped with many other metals to achieve the purpose of users.。The simplest, most common brass is doped with zinc,This type is called ordinary brass。When more than two metal elements are above,Special brass。So,We can also call brass copper alloy。

Copper
Summary,:Bronze is pure copper,Due to a layer of oxide film due to surface,So it is also called purple copper。
Pay attention to it here,Bronze and copper and pure copper are copper,The most common call is brass,Its purity can reach 99%.,It's not a bit of pure copper.。
And brass is a copper alloy,It is doped with other metal refining,Its purity and brass are not more than。
For example, we add other metal elements after the waste red copper is refined.。Bronze if you want to make red copper,First, you have to remove other metals inside.。
Ordinary brass needs to remove zinc,Special brass needs to remove more,So the resulting brass can only be less。
Now you know why people who go to your household waste, why should you say that red copper is expensive and brass is cheap??

Ⅱ:What is the copper in ancient bronze??
You can't imagine how smart,Because I don't understand how they think of smelt bronze。Means of,This cognition,How is this idea??How do they know bronze smelting?This is amazing!
Bronze is the earliest alloy in the history of metal smelting。
See alloy,Everyone may understand,Isn't we said above?,In the refining of copper,Add another metal,So it became brass,The bronze is actually like this。
Not like this,Because the melting point is high,the most important is,Its texture does not meet the cast requirements,For example, it is melted after melting fluid fluidity,Ancient artificial artwork,Need good flowability。
have to be aware of is,The presence of bronze is convenient for casting,Bronze smelting melting point can be achieved at that time,But it is not in line with their casting requirements.,Therefore, you have to seek a requirement to achieve casting.。
Means of,one day,Ancient craftsmen stay in pure copper,Suddenly I thought that the metal inserted into other metals to reduce its melting point.,Can also increase its castability。He really made this,He really got a suitable metal,That is bronze。
Is this not magical??Don't this be shocked??
